• MacBook Pro can't see hotspot USB iPhone

  I regularly use the iPhone to create a WiFi personal hotspot to feed my MacBook Pro. It works fine over WiFi but not via the USB port. Says 'the cable is unplugged,' which is not true. I tried different cables to eliminate the thread as the problem.

  The Mac does not generally consider USB to be a network protocol.

  You have a reason why you think it should work?

• How can I start my brand new MacBook pro, but I do not know password which someone of the store to

  How can I start my new MacBook Pro? I do not know the password for someone to the store to put it on the laptop. How can I change? I don't even connect to the laptop but I didn't even ID Apple on this topic, but I have an Apple ID on other Apple devices. Please help ASAP

  If you start the macbook does show something similar like this video? https://www.YouTube.com/watch?v=_g-3me2VTGo

  For a mac for optimum operation, you need a apple ID (to download apps and updates on the app store).

  If your mac asks you a password at startup upward, you must return it to the store you bought it and ask to remove it.

  I hope this helps!

  1. the present proceedings is a diagnostic test. It doesn't change anything for the better or worse and therefore, by itself, will not solve the problem. But with the help of the results of the tests, the solution may take a few minutes, instead of hours or days.

  The test works on OS X 10.7 ("Lion") and later versions. I do not recommend running it on older versions of Mac OS X. It will do no harm, but it will not do not much good.

  Do not be put off by the complexity of these instructions. The process is much less complicated than the description. You make the tasks more complicated with the computer all the time.

  2. If you have already a current backup backup all data before doing anything else. The backup is needed on the general principle, not because of what anyone in the test procedure. Backup is always a must, and when you encounter any kind of problems with the computer, you can be more than the usual loss of data, if you follow these instructions or risk not.

  There are ways to back up a computer that is not fully functional. Ask if you need advice.

  3 here is instructions to run a UNIX shell script, a type of program. As I wrote above, it doesn't change anything. It does not send or receive data over the network. There is no to generate a report on the State of the computer human readable. This report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents for me or someone else.

  You should ask yourself if you can believe me, and if it is safe to run a program at the request of a foreign national. In general, no, he's not sure, and I encourage it.

  In this case, however, there are ways for you to decide if the program is safe without having to trust me. First of all, you can read it. Unlike an application that download you and click to start, it is transparent, so any person with the required competence can check what it does.

  You may not be able to understand the script yourself. But variations of it have been posted on this site of thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. One of the million registered users to have read the script and set off the alarm if it was dangerous. Then I wouldn't be here now, and you would not be reading this message. See, e.g., this discussion.

  Another indication that the test is safe in this threadand this onecan be found, for example, where the comment in which I suggested it was recommended by one of the specialists of the communityApple, as explained here.

  However, if you cannot satisfy yourself that these instructions are safe, do not follow them. Ask other solutions.

  4. here is a general summary of what you need to do, if you decide to go forward:

  ☞ Copy a particular line of text to the Clipboard.

  ☞ Paste into the window to another application.

  ☞ Wait for the test to run. It usually takes a few minutes.

  ☞ Stick the results, which will be copied automatically, in a response on this page.

  These are not specific instructions; just a glimpse. The details are in parts 7 and 8 of this comment. The sequence is: copy, paste, wait and paste it again. You don't need to copy a second time.

  5. try to test in conditions that replicate the problem, to the extent possible. For example, if the computer is slow intermittently, run the test during a downturn.

  You may have started up in safe mode. If the system is now in safe mode and works pretty well in normal mode to test run, restart as usual before running it. If you can test only in safe mode, this.

  6. If you have more than one user and a user is affected by the problem, and the user is not an administrator, and then run the test twice: once under the affected user and one administrator. The results can be different. The user that is created automatically on a new computer, when you start it for the first time is an administrator. If you are unable to log in as an administrator, verify that the user concerned. More personal Mac have only one user, and in this case this section does not apply. Don't log in as root.

  7 load the linked web page (the site "Pastebin.") The title of the page is 'Diagnostic Test'. Under the title is a text box, headed by three small icons. The right one represents a Clipboard. Click on this icon to select the text, then copy to the Clipboard of your computer by pressing Control-C key combination.

  If the text is not highlighted when you click the icon, select it in triple - click anywhere inside the box. Do not select the whole page, just the text in the box.

  8. start the Terminal application integrated in one of the following ways:

  ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

  ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

  ☞ Open LaunchPad and start typing the name.

  Click anywhere in the Terminal window to activate it. Paste from the Clipboard into the window by pressing Command + V, then press return. The text that you pasted should disappear immediately.

  9. If you see an error message in the Terminal as "Syntax error" or "Event not found", enter

  exec bash

  and press return. Then paste the script again.

  10. If you logged in as an administrator, you will be prompted for your login password. Nothing displayed when you type. You won't see the usual points instead of the characters typed. Make sure that caps lock is turned off. Type carefully, and then press return. You can get a warning to be careful. If you make three unsuccessful attempts to enter the password, the test is still running, but it will produce less information. If you do not know the password, or if you prefer not to enter, just press back three times at the password prompt. Yet once again, the script will run.

  If the test takes much longer that usual to run because the computer is very slow, you can be prompted for your password a second time. The permission you grant by entering it will expire automatically after five minutes.

  If you are not logged as an administrator, you will be prompted for a password. The test will run. It just will not do anything that requires administrator privileges.

  11. the test may take a few minutes to run, depending on the number of files you have and the speed of the computer. A computer that is abnormally slow may take more time to run the test. During execution, a series of lines is displayed in the Terminal window like this:

  [Process started]

          Part 1 of 4 done at … sec        …        Part 4 of 4 done at … sec

          The test results are on the Clipboard.

          Please close this window.

  [Process completed]

  The intervals between the parties will not be exactly the same, but they give an approximate indication of progress.

  Wait for the final "Process complete" message. If you don't see it in about 15 minutes, the test probably won't be all within a reasonable time. In this case, press the Ctrl + C key combination or the point command to stop it. Then go to the next step. You will have incomplete results, but still something. If you close the window of the Terminal, while the test is still running, the partial results will not be saved and you have to start over.

  12. when the test is finished, or if you have stopped it because it was taking too long, leaving the Terminal. The results have been saved to the Clipboard automatically. They do not appear in the Terminal window. Please do not copy from there. All you have to do is start a response to this comment and then paste it again by pressing Command-V.

  At the top of the results, there will be a line that begins with the words «Start time.» If you do not see, but rather to see a mass of gibberish, you don't expect the "Completed" message is displayed in the Terminal window. Please wait and try again.

  If personal information, such as your name or e-mail address, appear in the results, make anonymous before posting. Usually it will be not necessary.

  13. in the validation of the results, you see an error message on the web page: "you have included content in your post that is not allowed", or "the message contains invalid characters." It's a bug in the software which manages this website. Thanks for posting the results of the tests on Pastebin, then post here a link to the page you created.

  If you have an account on Pastebin, please do not select private in exposure menu to paste on the page, because no one else that you will be able to see it.

  14. This is a public forum and others can give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but what're told you to do maybe not. For others who choose to run it, I do not recommend that you view the results of test on this Web site unless I ask.

• Trackpad MacBook Pro late 2011 does not not after upgrade

  I just update the OS in my MacBook Pro (late 2011) which worked perfectly well 'El Capitan' to 'Sierra '. Everything went, smooth and pleasant. but now, the trackpad is completely erratic, is in itself (such as move and open programs like possessed). I tried several suggestions from apple such as checking for updates, check the settings, delete all the gestures, etc. I'm assuming that the material is very well that was perfectly fine yesterday... any suggestions please help.   -Note; I have to use an external mouse, and the latter is very well.

  Hello Med_,

  Thank you for using communities of Apple Support. It is my understanding that after upgrading to Sierra, your MacBook trackpad has become erratic. I know that my trackpad is an important part of my daily use, I can certainly understand your concern. I'm here to help get this resolved with you.

  You did an excellent job so far! Then I recommend the system management controller (SMC) reset. This system can solve some unexpected behaviors. Follow the steps below:

  1. Stop the Mac.
  2. Unplug the MagSafe from Mac power adapter.
  3. Remove the battery. (Learn about removing the battery in the MacBook and MacBook Pro computers).
  4. Press and hold the power button for 5 seconds.
  5. Reconnect the battery and the MagSafe power adapter.
  6. Press the power button to turn on the Mac.

  The LED on the MagSafe power adapters could change State or temporarily disable when you reset the SMC.

  Reset the management system (SCM) controller on your Mac.

  If the problem persists, test this problem in safe mode. This will allow you to exclude the software as the cause. To help get started in safe mode and additional steps, use the steps and the link below:

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

  After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

  To leave safe mode, restart your computer without pressing any keys during startup.

  Try safe mode if your Mac does not end commissioning

  See you soon!

• MacBook Pro won't start not

  Hello

  I have a MacBook Pro that, if I'm not mistaken that I bought in 2009. So, last week I had several open files and I was typing on a Word document, I typed whenever he got more lag. Then my laptop just turned off automatically and I received a message (I don't remember very well what it read) and after that I tried to turn it on again, the start bar just loaded up to half, he stayed there for 10 minutes, then the computer is turned off again. Help, I can't lose the files that I had in this computer. What should I do?

  Thanks for your help.

  Try SMC and NVRAM resets:

  Try a safe boot:

  If no success, using the original installation CD and see if you can start the MBP.

  If you can, after the language selection, the display should have a top menu bar.  Click on UTILITIES and select and run disk utility > first aid.  If the disk cannot be repaired, a new will be necessary.

  If you cannot start with the installation diskettes, make an appointment at an Apple store genius bar for a FREE evaluation.

  Ciao.

• my macbook pro retina display will not download large files

  I had this problem happen to me twice before involving 1gig zipped files or files unzipped pretending to be finished in the download bar. It shows for example 309,5 309,5, the loading bar does not disappear. I try to click on it and it tells me "this son is still downloading. So I get in my downloads folder, click on the contents of opened, I look for the file and click on it like that, it gives me the possibility of reactivation of the zip folder, I do this, then it gives me an error message saying "files are not completed. (I give him hours and hours to 'finish loading' and then try again)

  Then... This has been recently. The first file I wanted to download was the Creative Design Premium Adobe (I waited half a day until the next day for this download click again on it) that is given to me directly in the downloads section of the adobe.com site. I need to reinstall the software due to an unknown error (YOSEMITE LIKELY) anyway... I start downloading, it ends - but not really. Something is happening. So I try it on Chrome, same problem. So I try it on a PC - made. No worries.

  So far I have not seen this question arise with someone else.

  The zip in question file is .7z and 335.9 MB file and the creative design premium is a 3.76 GB .dmg. I am running Safari on a

  MacBook Pro (retina, 15 inches, end of 2013)

  10.10.1 Yosemite

  MacBook Pro, Mac OS X (10.7.5)

  Start in Safe Mode, no doubt also resets of LANDAU and SMC , and then restart your computer normally.   See if the problem clears.

  If there is no anti-virus or anti-malware tools installed, any improvement in performance, of cleaning cache, optimizers any system or other such tools add-on, remove all those who, according to the instructions of the specific package.   Try the download again.

  Try downloading on a different network.   If it is a company or a network of offices, there may be filters and monitors in place, which can cause problems with the downloads.

  If all else fails, after the release of Etrecheck, and we will look to the configuration and what is installed.
