My MacBook Pro keeps freezing (spinning wheel) even after clean install of OS X

Hello all,

After 2 years of usage, my Macbook Pro started giving those beachballs with some applications (like Preview, Mail, Safari, MS Excel, Notes, Text Edit) not responding (I can see that in Activity Monitor for some time /1 or 2 applications not responding at a time) and then they get back to normal but after some time they or some other applications freeze again, and it's over and over again all the time. I have done pretty much everything what you can see here: http://www.wikihow.com/Stop-Your-Mac-from-Freezing-Up without any and even after clean install of El Capitan I keep having the same problem (I really hoped that clean install would help but it did not at all).

Does anybody maybe had a similar issue and/or could help to solve mine? I'd appreciate any assistance.

Igor

MacBook Pro, OS X El Capitan (10.11.4), null

Reset the System Management Controller (SMC). If there's no change, you've ruled out everything except a hardware fault.

Make a "Genius" a ppointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.

Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Keeping your confidential data secure during hardware repair

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

*An SSD doesn't need to be zeroed.

We had heard (after upgrading) that some "older" uMacs has problems after installing El Cap, but do you think CleanMyMac3 could have played a part?

That is difficult to answer authoritatively. The problem is that AV applications do not belong on Macs. They will often generate 'false positives' and in some instances delete items that should not be.

Ciao.

Hello Thalgk,

I had the same problem with my MacBook and I followed the same procedure as you did. Eventually I got a new SSD but the problem remained. Then I tried using an external SATA to USB cable and booted my MacBook externally and it worked perfectly - both with the old HDD and the new SSD. So it seems like the problem could possibly be with the SATA cable inside.
