Nervous about the upgrade to El Capitan!

Need input, OS X 10.9.5, computer works fine most of the time. Should I upgrade or leave it alone. Don't want to screw up my computer. Read the "reviews" on the App Store and I hesitate. Ned first hand experience.

Thanks in advance.

Before any update always create a backup. How to create a clone of startup

This way you can always fall back if necessary.

I have not had any problems upgrading to El Capitan.

    After the upgrade to El Capitan 10.11.5 shift, Alt and command of my keyboard keys started to act arbitrarily, they are suspended and do not work properly (I already tried several keyboards and is not Firefox or Chrome).

    Start safe mode and see if there are still have the problem there. Safe mode is slow and some things do not work, but it prevents some third-party boot loading software. If your keyboard works properly in Mode without fail, this would imply that some third-party software is causing the problem. If so, check the updates.

    It also takes more time to start because the BONE is clean some system caches that can also help.

  • After the upgrade to El Capitan cannot insert CD/DVD in external drive

    Hello

    I have a Macbook Pro (mid-2014 retina) and I have this problem since I upgraded to OS El Capitan. Now I have the last 10.11.5.

    I can't insert a CD/DVD in the external DVD drive. It gets stuck at the end when it is like 80% already.

    I searched on the web before and there was a workaround solution that you put the CD in and reboot and it would work and it is indeed, but it's a pain that every time I work on the Macbook and in the middle of something and I want to insert a CD that I have to close everything and restart to get the disc inside!

    Once I do that, it works fine and I can eject and insert it again normally, but the first time I have to restart first, and since it's an external drive, I have connected it all the time, so whenever I connect it, I have to redo this same process.

    I was hoping with the last update that this problem could have been resolved for me obviously it's a software problem because it came with the upgrade to El Capitan, I've improved in later, but still problem is there. I hope that someone would have reached a permanent solution for this and I would be really grateful to know it.

    Thank you!

  • A lot of cookies since the upgrade to El Capitan

    With the Mountain Lion, I'd end up usually with 15 to 20 cookies.  Since the upgrade to El Capitan, and using the same sites, I find myself with cookies from 80-90.  The cookie setting is "allow Web sites I visit."  I was wondering if I need to change something or if I missed a setting.  (I've been clear all cookies after each session.)

    Try each of them in order. A test to see if the computer works properly:

    1. Reset the PRAM
    2. Reset the controller (SMC) system management
    3. Start the computer in Safe Mode, and then restart normally. It's slower than a standard home.
    4. Repair the disk by booting to the recovery HD immediately after the chime press keys control and R that the Utility Menu appears. Choose disk utility and click on the button continue. Select the withdrawal (usually Macintosh HD) volume entry of the list to one side.  Click first aid button in the toolbar. Hold the button brings up. Disk utility and return in the Utility Menu. Restart the computer from the Apple Menu.
    5. Reinstall OS X by booting from the Recovery HD using the command and R keys. When the Utility Menu appears, select reinstall OS X and then click continue.
    6. Download and install updated Combo OS X El Capitan 10.11.4.
  • A few questions about the upgrade on Satellite A300-144

    Sorry for the typos, English is not my mother tongue.
    I want to ask some questions about the upgrade of a300-144.

    * Some info first.*

    CPU: T2370 ([http://ark.intel.com/products/34445/Intel-Pentium-Processor-T2370-1M-Cache-1_73-GHz-533-MHz-FSB]).
    Chipset: GM965 ([http://ark.intel.com/products/29821/Intel-82GM965-Graphics-and-Memory-Controller]).

    * Questions.*

    1. my frequency of laptop memory at 533 MHz, supports 667 MHz memory controller, memory modules can work at 667 MHz. Is - this because CPU FSB 533 MHz frequency and new processor at 667/800 MHz FSB will fix it or it is hardcoded in the BIOS?

    2 Intel said that the size of max memory for my chipset is 4 GB (2 x 2 GB), but Toshiba says that only 2 GB (2 x 1 GB), who is right?

    3 I know, taken of my CPU is μFCPGA-478 aka socket P, max FSB 800 MHz, max 35 W TDP, so T9500 ([http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB]) is a compatible processor or there are some limitations in the BIOS?

    > 1. My frequency of laptop memory at 533 MHz, supports 667 MHz memory controller, memory modules can work at 667 MHz. Is - this because CPU FSB 533 MHz frequency and new processor at 667/800 MHz FSB will fix it or it is hardcoded in the BIOS?

    The speed of the memory is related on the material. This means that the FSB is responsible for the limitation.
    If the FSB would allow support 667 MHz then the memory would also at this speed.

    > 2. Intel says that the size of max memory for my chipset is 4 GB (2 x 2 GB), but Toshiba says that only 2 GB (2 x 1 GB), who is right?
    The memory depends on the chipset. So if the chipset supports 4 GB of RAM, you should be capable of this move to 4 GB of RAM

    > 3. I know, my CPU is? FC-PGA-478 aka socket P, max FSB 800 MHz, max 35 W TDP, so T9500 (http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB) will be a compatible processor or there are some limitations in the BIOS?

    It might be possible that the new processor would be fully supported by the BIOS, but in most cases it should not be a problem if the chipset would support the new processor.
    But as far as I know the upgrade of the CPU is not supported by Toshiba or any other manufacturers of portable and its your own risk to run laptop with the new processor.

    Yesterday, I downloaded the upgrade to El Capitan in a Mac Pro (early 2008) running Yosemite 10.10.5, and today I can not start the upgrade.

    The only option I have found is to click again on the download button, but the circle of download rest bike for a long time and ultimately that nothing happens.

    Start with CMD + r or the Option/alt key to boot from the recovery partition & use utility disk from there to repair the disk, and then repair permissions.

  • Since the upgrade to El Capitan, I can't add printers!

    Since the upgrade to El Capitan, I can't add all the printers on my Mac. I have a MacBook Pro. I deleted my printer list and restarted my computer. I have reset my system print and restarted my computer. Whenever I have to add the correct IP address to my tab "add a printer", I get the same notification:

    If I type 'continue', the rest in the queue and automatically default print job is "suspended." Everyone at the office (PC and Mac users) do not have all the adding problems or printing to the same printer with the same IP address.

    This was never a problem until I had updated the operating system of El Capitan. Help, please!

    Use ppd installers for v 10.11 2.2.0.0 manufacturer.

    1. no data not wil drop in time upgrade or I do a backup copy be sure.

    2 wil that any software that is installed before the upgrade for example antivirus, office 2010 wil be on the computer after the upgrade? or what I need to install again!

    3 when I do an upgrade must I pay online for the new version?

    answers very short wil suffice.

    Thank you

    Johan

    1. your files should be kept in an upgrade, but we always recommend making a backup to be sure.

    2. your software will be kept, but as with #1 above, we recommend to always have your install CD/file available to be safe in case you need it.

    3. you can buy the edition of Windows 8 Upgrade from a store or online, Yes. It is not free.

  • MacBook Pro has started to randomly stop when it is on battery since the upgrade to El Capitan

    I have a MacBook Pro (15 inch, early 2011) which works very well on the Mountain Lion for a long time. I finally got round to upgrading to El Capitan last week: directly to 10.11.6. A few days later he just powered down without warning while I was working. He was so very well for a few days, but then made several times in the last 48 hours.

    I am moderately sure it happens only when it is on battery (it did not in the past hours 8 while that plugged). Whenever it happens, that there is no warning and the Mac then fine restarts (manually) - Although the clock resets always in 1970 until he can contact an NTP server. One of the curious side effects is that my PostScript fonts were blank on the screen in Excel for a few reboots yesterday but then OK once again!

    No hardware has changed. Major software change is only El Capitan and possibly an iStat Menus update.

    I have reset PRAM and SMC. I ran the short AHT. I disassembled the machine and clean the fans. they were OK, but the problem seems to occur when the Mac is hot.

    Spotlight and Time Machine sometimes seemed to be struggling for the upgrade, and I also saw rpcsvchost with 100% of a core for a while. The machine feels sometimes slow - but for the last 8 hours, it was very good. The only model that I put in place, is that it seems to occur only on battery; It's even happened then that the Dock (etc.) were loading after logging in after an unexpected shutdown.

    The other thing common is in the newspapers every time:

    Cause of previous stop:-128

    I scanned a number of related posts to aspects of it, but do not look at who blames El Capitan rather than material. Yet, many people reported this kind of problem after the upgrade... Coincidence?

    Any ideas?

    Thank you.

    Cause of previous stop:-128

    A negative stop code generally indicates a hardware failure. Have the Apple to assess your Mac. The fix may be as simple as a spare battery.
