The more people upgrade to macOS Sierra, the more issues are being discovered. Most of them relate to the decrease in the speed of work and overall system crashes. People deck out Apple computers with the most recent versions of operating system hoping to get the boost in performance, but they sometimes forget about some major moments.
Despite the small problems a Mac owner may face after another OS release, you should focus on the advantages every new version offers. Be patient, and you will benefit from upgrading to macOS Sierra or High Sierra.
For starters, try to implement the offered solutions to prevent your Apple computer from freezing.
It may happen so that the computer becomes unresponsive right after startup on a newly installed macOS Sierra. The exact reason for that remains unclear. Yet, on the Apple Discussions, several users claim that the issue could be caused by antivirus apps that have not been deactivated or removed prior to the OS installation.
Anyway, whatever the reason is, the working solution is to start up in Safe Mode. This action repairs the corrupt system files without having to erase user’s files, apps, and other types of data. Once you are done, try installing macOS Sierra/High Sierra again. Another good idea is to switch from a Wi-Fi connection to a wired one.
Does your Mac get stuck on the login screen? It is another typical problem of macOS Sierra. “Have you tried turning it off and on again” method (hail “IT Crowd”!) works best here. Shut down the system, disconnect all external devices and restart your Mac in the Safe Mode. If it does not help, you may contact the official Apple Support. In case you face something unusual and weird, post a report for the detailed evaluation and possible solution at this website.
Except for the Sage Mode, you may also try these steps:
1. Resetting PRAM:
2. Checking HD with the help of Disk Utility.
Reboot your Mac and hold down the Command+R keys. You should notice a Recovery tool screen soon. Choose Disk Utility and pick the First Aid tab. Choose the hard drive from the sidebar and push the Repair button to analyze and fix the disk. The system might recommend reformatting the HD if it has serious problems.
3. Rebooting in Recovery Mode & reinstalling macOS Sierra/High Sierra.
To restart and reinstall the operating system, start up with Command+R keys. You should not release the keys until the company’s logo pop up. The appearance of the Utilities window means the bootup process is over.
Once the user starts up from macOS Recovery, he/she should pick from these utilities. After that, press Continue. Restore from the Time Machine backup. Next, download and reinstall macOS Sierra or High Sierra.
Have you noticed macOS Sierra freezing or crashing after the Sleep Mode? Try unplugging the external monitor – you may wonder, but Mac’s monitor might be the culprit! A user may spend some time figuring out whether the freeze is a hardware or software problem. Instead of wasting your time, try one of the effective solutions.
A user who deals with a non-removable battery should turn off the computer first. Then:
A user whose Mac’s battery can be replaced should start with switching off the machine and disconnecting the power adapter as well, but then just push the power button to switch on the device. That’s it!
Repeat the steps described in the previous section of the article for this task.
The final solution to consider is, perhaps, the fastest, simplest, and most effective way to prevent Mac from freezing. Are you intrigued?!
Your computer may constantly be freezing due to the lack of space. Many different factors cause it, but the junk files are the root of all evil. They include outdated items, large files, duplicates, cache, cookies, temporary files, login items, etc. In other words, those are the items a Mac owner does not need any longer but forgot to delete. Some of such files are hidden from the naked eye. That is why you will need some help here.
There are several ways how a user can solve the issue with the help of built-in utilities. However, instead of wasting your time and nerves, it may be a good decision to download and install a third-party cleaner. You may find plenty of such software on the Apple market today.
Once you launch the cleaning app, you will understand what to do thanks to the simple, user-friendly (as a rule) interface. The app will scan the entire system searching for the duplicate files and other types of junk, uninstall the apps you do not need any longer (upon your request), and wipe the hard drive. That is the easiest and the quickest method to speed up your Mac and prevent it from freezing over and over again!
