iMac freezes after upgrade to Mac OS Sierra

I have a 27 iMac late 2009 ". After the transition to macOS Sierra, I got freeze about once or twice a day. The only way to get the system operational is again via a cold start. In this case, the pointer of the mouse still works, but otherwise, the system is not responding. I have never had this problem in 7 years using the same material, so a bit of a loss.

How much RAM you have installed? You can check in the  menu > about this Mac. Slopes of the Sierra, but barely, with 4 GB, but it really needs min. 8 GB runs correctly.

You can also try Safe Boot mode.

-------

Restart in Safe Boot mode by holding down the SHIFT key at startup. Secure boot is quite slow because the operating system performs some cleanup and verification tasks, so give it time. Once you're completely connected, restart normally.

  • Not able to scan with the preview after upgrade from Mac OS Sierra...

    After upgrading to Mac OS Sierra. I'm unable to use the preview to scan.  Before this upgrade, it worked fine.  The HP scanner software does NOT work something like OS 10.8 or 10.9.  Preview worked perfectly so far.  If anyone knows how to solve this problem, your contribution will be greatly appreciated.  Thanks in advance.

    Have you tried scanning with Capture of Image instead? It worked for me.

  • Configuration error 1 after upgrading to Mac OS Sierra (Illustrator)

    Hello world

    After that I have upgraded to Mac OS Sierra, some of my Adobe software started crashing. Adobe Acrobat XI opens but unexpectedly stops after a few seconds. But above all, Illustrator does not start. I get the Configuration error message (error 1) and suggested to uninstall and reinstall the software (which doesn't help).

    I tried to change the permissions for the files SLStore and Adobe PCD. And indeed, the permissions for Adobe PCD have been set to read only for the admin.

    Unfortunately, change the permissions did not help. I get the same error message. Also, once I have reinstall the software, change the permissions to read-only.

    It happened just after upgrading to Mac OS Sierra. I have no backup, so downgraded to El Capitan is not an option.

    Please help, the standard solution has not worked for me and I need Illustrator to survive.

    It's the iMac and MacBook Pro. The two machines are powerful and new.

    After the upgrade to the new MacOS Sierra seems incredibly slow on everything that Dreamweaver. Create a new page.

    The last time I had problems with Dreamweaver was energy, it has been fixed in an upgrade later. This time the problem is something else.

    Mode Live View shows not alive, must constantly keep Refresh and it's incredibly slow when it works.

    After a short then nothing works and you must restart Dreamweaver. It is a problem between the application and the system. Will it be fixed in the near future by Adobe or should I go the road big return to the old system.

    Thanks for all replies.

  • Can't stop MacBook Pro after upgrade to Mac OS Sierra

    Yesterday I had upgraded my MacBook Pro since OS X El Capitan with macOS Sierra. Unfortunately I can't stop him, I can't even restart. Whenever I have start/stop I get a black screen (no slider) and it remains frozen. I have to hold the power button for a few seconds so that he will stop. I want to avoid cleaning the installation and configuring everything. Does anyone have an idea what causes this problem? I cleaned the cache and reset the NVRAM without effect.

    ... I cleaned the caches

    I recommend that you do not have this, especially with a 'clean' non-Apple utility. All these things can do is cause problems. A SMC reset will remove some files from the system cache: reset the management system (SCM) controller on your Mac. That's all that anyone should ever do.

    Back up your Mac if you have not already done so. Read https://www.apple.com/support/backup/to learn how to do this please. To learn how to use Time Machine read to use Time Machine to back up or restore your Mac.

    Then, shut down your Mac and restart in 'Safe Mode '. To learn how to do it please read: try safe mode if your Mac does not start-up. Compare works your Mac in Mode for how safe it was.

    Then restart normally. If the same problem comes back, please read the section If a problem does not occur in safe mode for actions recommended to Apple.

    Finally, you can temporarily create a new user account and log into this account to determine if the problem also exists when connected to this account.

  • Google Earth opens after upgrading to Mac OS Sierra

    Since the download and installation of maOS Sierra I find Google Earth does not work?

    see the following topics

    https://productforums.Google.com/Forum/#! rBa2c_LjgMI/cards/subject

    If the software is still not compatible, you must communicate with development of google and see if they plan to release a new version. Or if you have a Time Machine backup, you can restore your system to a point where the operating system and this app worked together. Past that Apple has no googles software and does not patch their OS to accommodate other developers especially when OS X 10.12 was available to google for months to make these changes.

  • At startup, the Apple iMac logo flashes red after update to Mac OS Sierra

    After upgrading to Mac OS Sierra, my 2015 iMac 21.5 retina has a flashing red Apple logo, then a brief splash screen flickering when starting. Once started, the computer seems fine, with no obvious debris. I don't know why the logo flashes red and then the screen flickers - bad drivers; a problem of software in the start-up phase; a problem with the drive of the merger; or maybe some other gremlin? A quick search on the internet reveals that at least a few others have the same problem with this version of the OS, and it seems to have occurred in the years spent with any other version of Mac OS upgrades. But there is no good answers on how to fix this. I rebooted several times hoping it would clear itself, but no luck.

    Safe Mode boot removes the system caches that can help after an update or upgrade.

    Follow these steps to start in safe mode.

    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.

  • After upgrading to MAC Mountain Lion, the drivers for my HP C4680 were removed (accidentlly)

    After upgrading to MAC Mountain Lion, the drivers for my HP C4680 have been deleted (accidentally). I downloaded the drivers from HP, but my Macbook it not install because the drivers are not available on Mac Store. How can I get the printer installed?

    Hello

    First of all, make sure you restart your Mac, and then try to add the printer again.

    If it persists, ensure that the USB port directly connected to your Mac and not via a USB hub or extention.

    Ensure that the USB is not longer than 2 m and check to see if that can help you.

    Also, if you have an iMac, be sure to plug the USB in the port at the back of the Mac and not in the Apple keyboard, which is not powered.

    Also, try to reset the printing system, then try to add the printer and check any changes:

    * Be aware that reset the printer system will eliminate any existing queue and reset all custom settings driver.

    Click on the Apple menu and then click on System Preferences.
    Select Print & Scan.
    Right click (or Ctrl + click) your product with the Printers list in the left panel and then click on reset printing system.
    Click OK to confirm the reset.
    Type your user name and password.
    Click OK. The printing system resets.

    Now, click on the Plus sign and try to re-adding the printer.

    If none of the steps above does not lead to any progress, go to the library and place the HP folder to the trash.

    Enter PPD\Contents\Resources, search for C4600 and move the files to the trash, then try to add the printer again.

    Hope that helps,

  • Why the back my mail list, text and phone iphone 6 freeze after upgrade ios10

    Why my list of e-mail, text and phone iphone 6 freezes after upgrade ios10?  Have you tried to turn it back on.  Becomes a real pain in the uknowwhat.

    I had the same problem at first but I was testing the first version of ios 10.  but the reason may be due to the low storage? If your storage space is ok please go to settings then general try to look for the software update again just to make sure that you use the latest version of ios usually there a few times an update immediately. If none of these solve the problem, try now button the power button and the home button at the same time (the screen of your iphone turns off a few seconds) touches both simultaneously when you see the apple logo on your screen if all else fails you can try connecting your device to itunes on a pc and run a quick diagnostic test? you go to itunes on a pc if you have already installed on your pc, laptop etc... Look at the upper left side... Click the help... Go to the bottom of the list to "Start the diagnosis" (make sure that all the test boxes have a tick and click ok to run the test) PLEASE NOTE your iphone you will need to be connected to the computer before hand... hope this will help you know if there is a problem, but when I came across this problem with my camera it was because my storage was almost full on my device and in icloud if This is the case then you need to maybe buy more storage or delete applications or games, you do not use this should help solve the problem of storage (if your device is low on storage)? hope this helps somehow.

  • 120 all-in-One desire: analysis of the problems with envy 120 all-in-One after upgrading to Mac OS 10.12 (Sierra)?

    Hello world

    My operating system is Mac OS Sierra 10.12, but the drop of HP does not include yet - that's why the "other" operating system.

    I just upgraded my Mac to 10.12 Sierra, and I've also updated software from my desire to 120. I have also reinstalled the HP utility software on my Mac. And Yes, I restarted my Mac several times too.

    Now, the challenges:

    1 120 feel like in his screen it does not find my computer when I try to scan to the computer. As if he cannot see it, even if the two computers and 120 are on the same network. This problem is new and was held just after the upgrade from Mac OS.

    2. Furthermore, when I try to activate the scan on my Mac computer, an error message appears telling me to update my software HP (see screenshot), although I've done.

    If someone had the same problem, and if you have, how you go about it?

    Thank you.

    Hello

    HP software full functionality is not yet available for Sierra, as you mentioned the ysstem functioning is not yet.

    You can scan with the application of ICA Apple (Image Capture or sweepers & Scanners), as well as thorugh HP Easy Scan you will experience, however, some issues you described, as this behavior with the scanning of the façade, this is a known issue with the software that should be fully updated for Sierra soon, it should be available soon, assuming that during the next weeks to come...

    You can insall HP Easy Scan 1.6.1 below and check if you are able to scan from it:

    Note: If there is already a HP Easy Scan of a previous version icon in the Applications folder, remove and empty the tash first.

    http://FTP.HP.com/pub/softlib/software12/HP_Quick_Start/OSX/installations/Essentials/HP-easy-scan-1_6_1.pkg

    Then, try to scan using HP Easy Scan and check if it works.

    If the front panel can now list your Mac, it probably, work if not to use the Scan on your Mac software for now.

    Kind regards
