  • Clean install El Capitan

    Mac Min (end 2012) with OS 10.11.4

    After almost 4 years of loyal service, my Mac Mini has crashed. I have restored from Time Machine (Time Capsule). It took 3 days! It does not restore Mail and delete my account administrator a second restoration took 2 and a half days. Had a lot of problems after a lot of troubleshooting so I started the thread. I reinstalled El Capitan (not a clean install) of Apple and restored from Time Machine. It seemed to work after some difficulties of retrieving mail. I discovered that my account has been "standard". Not an administrator account. That's when I discovered that users & groups so that security preferences would not have been responsible and preferably errors windows generated. I reinstalled El Capitan again and the preferences panes issues are now fixed. It seems now that my basic problem is that I don't have an administrator account. As advised on the User Forums, I started using Cmd + S in Single User mode terminal where I should be able to create an administrator account. However, the terminal dΘmarrage aprΦs, I am unable to enter required text strings? I seem to be at an impasse.

    I seem to have discovered that my problem might be that my administrator account has no password (I wanted a quick no start-up of the action).

    I resolved to the fact that I may have to do a clean install. My question is if if I wipe the drive and re-install El Capitan, create an administrator account, and then retrieve the Time Machine backup and wait for all my applications (Parallels, 10 Windows, MS Office) get resettled.

    Any advice?

    Ron

    Yes, you can do it. Use Time Machine to back up or restore your Mac - Apple Support

    I would rather a clone, but you already have corruption. Do not forget to save a TM time frame is before you had corruption.

  • question to iCloud with El Capitan

    I searched but could not find a relevant answer.   I recently did a wipe on my Macbook air and clean installed El Capitan.   But every time he asks me a different password of my iCloud.   When I got to the control panel user account and click on change password I don't get a pop - up asking if I want to use my password to iCloud.   It gives me the standard change password screen instead.   I logged onto my account iCloud and all that it works.   Don't know if it's something else I'm missing or what.   Any help on this would be appreciated.

  • Can I reinstall an app that I bought from the app store after a clean install of El Capitan?

    Hi all

    I did a clean install of El Capitan, which made my 2011 macbook pro currently unusable.

    A few days after installation I met problems I've ever had before. Baffled because since my drive hard worked completely fine with the Mavericks and Lion. No disk ever utility error. Computer froze a couple times the 5 years ive had the it. It has been stable.

    I explained my failed attempts to solve this problem in another thread here.

    So, if this is not relative, which seems to be caused all of this, I concluded it's a failing hard drive?

    My question is the only program of value I have logical hard disk Pro X (bought and downloaded 3 days ago) so anyway, given my problems with the hard drive I have can always reinstall logic after I got a new drive and reinstalled OSX?

    I'm on a PC at the moment and looked everywhere to find my purchase history of Logic Pro X. The only thing I can find official is my receipt by e-mail. I logged on the apple.com site with my Apple ID and it show nothing bought for the last 90 days. Active iPhone and cant find a purchase history. This suggests to me that you need to check on a mac on the App Store?

    Yes. You will need to check and it redownload via the Mac App Store with the original ID of Apple.

  • Question seeks to clean install 10 Windows on the drive of the merger. El Capitan.

    Problem: try a clean install of Windows 10 via the Boot Camp Assistant on an iMac 27 inches (Late2013) with 10.11.4 installs hours (more than 8 hours) and then failed to install Boot Camp updates. Essentially installation take much long than normal and cannot install updates of the Apple software or create normally start Windows Boot Camp 10.

    Background: After problems of slowing down after upgrading to 10.11.4 (with improved Bootcamp Windows 10) who had previously worked fine for 10 months, to the point of a start of OS X time, I decided to do a clean install of my iMac with Fusion 3 to disk.

    As I was unable to remove the partition from Boot Camp through BCA because of his holding always at the same load, I used Internet recovery and reset the Fusion drive. This then required me to repair the partition of Fusion by car through THE "fix" option which seems to work very well. And reinstalled OS X 10.11.4 which works fine now (delays etc..)

    Try using BCA to create a new partition Boot Camp and a clean Windows 10 install after downloading an image of disk W10 directly from Microsoft (Win10_1511_1_English_x64), BCA by downloading software updates and by selecting the desired partition, it began to restart and initialize the installation. However the whole process has been very slow, each step takes much longer than usual, to progress. Leave for hours rest a blank screen or with a circle of rotation.

    I tried with another stick USB 3 and also a USB 2 stick, but none has made a difference.

    In the last attempt, I left running overnight and after 8-9 hours, he finally reaches the top of desktop Windows 10 and the update of Apple Bootcamp starts to load updates. However, he just hung and even after 2 hours, nothing was. Reboot and try once again has been the same.

    After that I tried to create a Windows Installer via BCA 8.0 however it gives just a TPG error when you try to select the drive (due to el Capitan I guess?)

    After four days of efforts, I'm a loser on how to get the Windows 10 on the Boot Camp partition. I can't even install W8 and upgrade due to the error of TPG.

    Any help or suggestions how to proceed with the diagnostic / resolution of the problem would be appreciated.

    Details:

    System: iMac (27 inch, end of 2013), 3.4 GHz Intel Core i5, 16 GB 1600 MHz DDR3, NVIDIA GeForce GTX 780 M 4096 MB, OS X 10.11.4

    • Nothing other than the keyboard and mouse attached via the USB ports, as well as the key USB of BCA. No other attached devices.
    • Reset memory NVRAM, SMC and ran more than once disk utility. No problem not reported.  Ran NVRAM reset before each attempt.
    • At ran EtreCheck report which seemed OK.
    • Verification of diagnosis ran who is childless.

    A detail I noticed after the merger by car there are now two Macintosh HD images when you use boot option. One previously. Are named "Macintosh HD" and "Macintosh HD2". I remember being Yosemite simultaneously in three, but which has been fixed in an update.

    In addition, it seems that no recovery partition. Cmd + R lance Internet recovery.

    Summary:

    Q1: Should it take 4 + hours to install Windows 10 via BCA?

    Q2: Al must ultimately be so slow when initially W10 desktop?

    Q3; What I do once I arrive at the office of W10 but it automatically updates the graphics driver as BC update is simply suspended for centuries and get a working driver to restart at least W10?

    Q4: is there a problem with the disk HARD the Drive of Fusion that is causing all this delay and slow install / boot? ON the clean install OS X 10.11.4 it is back to be fast as usual and all tests show things are OK but W10 goes on the part of the HARD drive. No way to verify this beyond diagnosis or Etrecheck?

    Q5: Y at - it no problem with the GPT / MBR that may be causing the delay etc. ?

    Q6: How can I use my existing WindowsImageBackup backup from the previous W10 with the BCA install usb drive or how to create a USB stick otherwise recovery disk with my other single Mac have W7?

    Q7: How can I install W8 as I once did on Yosemite, via el Capitan without a mistake to TPG on selection of disc?

    Details:

    Day 5. Attempt at 6.

    Partition Boot Camp delete and try again install via BCA. First question, is that when the startup it goes to a blank black screen. For a time nothing left. Reset then using alt to select windows training results in almost instantaneous startup of the BCA message created and the beginning of the installation.

    4 1/2 hours from start of Windows 10 initial signature window.

    Then the second question. One to reach the Boot Camp update Office tries to start and install the drivers. Allows you to "list files...". "stage then sits at the bar about 5% green for 1 to 2 hours and does nothing. All actions in the Office of the W10 takes ages.

    In the meantime, auto update of the W10 appears a message saying that the updated graphics drivers as one of the few messages or actions during this period. Looks like Nvidia install with the entire package of experience (unwanted) etc. and very probably not the correct gpu driver.

    Finally deciding to cancel the installation of BC by killing the Setup.exe process. Then copy Boot camp install files on the desktop. Lasts 30 minutes to copy. Run again and this time, although taking 15-20 minutes to download and install later with the success message.

    Check the graphic driver it shows a yellow exclamation mark, so the following Microsoft instructions I use the uninstall option via the device and then Manager (slowly) come on board to load and download the latest Nvidia driver on their site for the GTX 780 M for 64-bit W10 etc. The same thing that I had used previously. Slow with running the Nvidia Setup program again, but eventually it works only to say that he could not install as unrecognized graphics device...

    He ends up with Microsoft PnP driver so it's at least sufficient start and run it again BC of the figure updates as all other drivers have been installed. To restart, but I get an error of K-Mode that is most likely related to this driver graphic and not possible to start in the new W10 Boot Camp partition after 7 hours.

    I have a picture of W10 backup recovery (WindowsImageBackup) I've had in a few weeks, but it will not install bet for the installed W10. I try with the ACO created the USB windows but can't seem to get a way to get into recovery mode and to get the menu to install it. I don't have a way to create a USB W10 recovery key now because my other Mac has just installed W7.

    Finally I tried to count a reset of the Recovery boot up option but it seems that it will take longer to start.

    I also went to the recovery and selected Boot Mode safe, but it opens on an empty black window and he's here doing nothing.

    Looks like I'll have to restart on via BCA and reinstall and try and solve the problem of graphics in order to install driver updates from BC and restart to W10 and hope that with the drivers, it returns to the operation and the normal starting time. Then update the gpu driver.

    I used and installed Boot Camp several times with over the years including previously an upgrade of W8.1 > W10 I used for over 6 months without problem. I've never known these installation very long or ice once in Windows even for the initial start upward.

    For any help or suggestion would be appreciated, and this seemingly simple process has now expanded to five days.

  • Clean install of El Capitan, causing all sorts of questions

    Hello

    I decided to do a clean install of El Capitan on my Macbook Pro 13 "retina end 2014 using sudo command to set up the USB bootable stick with the latest version of os x for the Mac Appstore. Installation of El Capitan appeared flawless in its execution and first start went well. Before the installation, I just formatted the disk by erasing the current drive and creating a new partition that I chose to implement the OSX on.

    Everything seems to be normal and familiar, until I try to log in iMessenger and FaceTime, which, in both cases, does not work after several attempts. Either I was told my internet connection has been lost or authentication failed. In addition to these connection problems, the overall performance of the operating system seems to be awkward and not nearly as smooth with my initial configuration to the factory system.

    I started to wonder if the current version of El Capitan available on the Appstore is flawed and broken? Someone else met weird performance / connection problems after doing a clean installation of El Capitan on their Mac recently?

    I can't use my Mac like this: someone in the support of Apple technology to address this issue now!

    Mike

    I did the same install clean, but the Apple server.  I'm having the same problem, however, there are several threads of people experiencing the same problem with the new OS X updated on El Capitan and some who use Yosemite said that they have the problem of too!  It is on the end of Apple

  • Free Windows 7 Upgrade Clean install questions

    Hi, I have recently buy a Mini 5101 it comes with XP Pro and Vista Business... I currently have Vista Business installed on it. I wonder about the process of upgrading to windows 7. On the free upgrade Web site it is said that the operating system can be upgraded to windows 7, according to the weather, I have vista (upgrade straigh) or xp (must be a stable cleaning). Now, my question is can I perform a clean installation with this upgrade? I know that normally you can perform a clean install via the insertion of the disc of the previous operating system media during installation, but as the Min 5101 is a netbook (no cd drive) I will probably install it via a USB key. It is very important for me to have a clean install.

    On the upgrade Web site, it says that if you are using XP pro, you must perform a clean installation. It would be better for me to install XP now order the update, and then install Vista so that I can get the version that will allow me to perform a clean installation - or I'd get the same disc anyway?

    I know the installation disc doesn't have not yet been outside and not so should know the process entirely. Kind of hope that someone will have knowledge on this subject.

    The installation media will allow you to perform a clean installation 'upgrade' using product key of the current operating system during installation. This allows him to check that you are upgrading from a previous version of Windows.

  • HP Envy 15 Windows 7 Professional clean install Driver questions

    This morning, I did a clean install of Windows 7 on my brand new envy 15 (LW897AV), which includes the deletion of backup partition as the partition driver HP.

    Unfortunately, many drivers not installed, and I can't find a way to find them. This includes Beats audio driver (I have the audio control panel, but it is not connected to the button on the side volume control) as well as the microphone and some drivers that appear in the devices Panel but the diagnosis is not able to find.

    Is there a way to fix this now, or should I cave and pay the $20 and get a recovery CD?

  • Clean install on new SSD?

    Hey people,

    New on the Apple Forum, hope it's ok to post this question here and in the forum of the iMac. My question:

    I recently acquired an older iMac Early 2008 (8.1). Currently it has 1 GB of RAM and a HARD drive that is extremely crowded. I just bought a 2x2gb memory kit for it, and decided that I had, I will do a clean full of Snow Leopard and then level installation to El Cap. So I bought a Samsung EVO SSD faithful and a SSD IcyDock Mount for it. I also bought a DVD of Snow Leopard from Apple, since I couldn't find the original. All that from the road, here's my question:

    I want to do an installation clean full of Mac OS X on the SSD, no cloning, no record of the files, nothing. The old HARD drive, as mentioned, is packed with the previous unwanted users. I read through loads of tutorials and whatnot on the web and can not find a concise answer to how to proceed. Some say it just install the SSD drive, format it with disk utility, and then start the DVD (not literally). Some say, create a USB bootable upgrade downloaded OS X .dmg file. And so on.

    Can someone tell me, as a former PC user, new iMac user, what to do in this situation?

    Question side: is it possible to go directly to El Cap instead of go through Snow Leopard to get there?

    What I have:

    -New Snow Leopard DVD

    -new SSD

    -old HDD (installed)

    -many readers of an inch, if necessary

    Thanks in advance!

    Make a USB of El Capitan key would be the easiest way to address the issue.

    First, install this RAM upgrade on the iMac, as you will need speed. Once you have done this, start the computer normally, open the app store and download OS X El Capitan from the Appstore, so you can do a flash USB drive out of it.

    Once El Capitan finished download, download DiskMakerX here

    http://diskmakerx.com

    This program will automatically create an El Capitan bootable flash drive that you use to install El Capitan on the computer.

    After the program ends and creates your USB key, turn off the computer, remove the old HDD and throw in the SSD you bought.

    Now that you've done all this, plug the flash drive into the Mac and hold down the ALT key and select the flash drive to boot from the flash drive and install OS X El Capitan on your mac.

    Once he finishes the installation, you're done! You will then be presented the OS X install screen and you're ready to start using your computer!

    I hope this helps! Answer please if you have any other questions.
