Thanks for letting me join! I have a mid 2015 MBP Retina, 2.2 GHz Intel Core i7, 16 GB DDR3. Sometime in mid 2019, it began to freeze for exactly 11 seconds on a random basis (seems random to me, anyway). Apple had me restart in Safe Mode, reinstall the OS, etc. and it continued to do that. I went to the Genius Bar in Tysons, VA (where I was living at the time) and they upgraded the OS to Mojave 10.14.6 from whatever I had, removed everything and put back only a few programs. Didn't fix it and I had to go home and use my Time Capsule to revert to what I had before I took it to them so I could have my MS Office and pretty much every other thing I used back. I have seen many people in the Apple Forums with the same issue and no useful response from Apple. Does anyone have experience with this particular issue?
Got a tip for us?

What are you doing when it freezes? Like what program, are you on battery or plugged in, are the fans running, etc? I have a mid-2015, though it is specced with the 2.5ghz CPU and dedicated GPU. Never had freezing like that (idk maybe it has frozen once or twice but it's been a solid machine).
I am experiencing this too, same machine that you have. Often when I'm just browsing normally in Safari—the mouse and entire system will freeze for ~10 seconds and then come back like nothing happened.
I'm convinced Apple doesn't care about the mid-2015 rMBP at this point.
I'm afraid I have been unable to isolate any specific program or condition that may be triggering the freeze. I check to see if it is using any resources more than usual, but nothing stands out. Thank you for your reply.

Yeah, I'm afraid their honest response would be to invite me to buy a new machine. But the freezes are exactly 11 seconds each time.
Are the fans running faster when it freezes? And have you tried running the built in diagnostics yet? Power down the Mac, then hold down the D key while powering it back on.
In addition, try resetting the SMC and PRAM:
SMC: https://support.apple.com/en-us/HT201295
PRAM: https://support.apple.com/en-us/HT204063
Thanks! I think this was part of the telephone advice Apple gave me, but I will try it again and report back.
Yep, same problem here. I thought it was because of my 3rd party ssd, but maybe not. Today it actually rebooted without warning, and had a second of static all over the screen, but seems to be working fine now. The freezes are really annoying.
OK, Diagnostics said no issues, I reset the SMC yesterday and the PRAM today, so far so good. I think when Apple had me do this it lasted 24 hours before freezing again. I'll report back if it pops up.
After the next freeze, open Console.app and check the system.log and the device errors & faults sections for any errors that coincide with the freeze.
It seems that based off of your efforts, you've ruled out software as an issue. If I had to guess, I would say it's a Hard Drive or Ram issue. If it were the logic board, I think you would have other symptoms / issues to accompany the one you have. Although, if a RAM issue, it's essentially a Logic Board issue considering you can't replace the RAM without swapping the Logic Board.
So far I don't think it has! One thing it does do now is show the black screen with white apple and the white progress line which I haven't seen in awhile. And it's kicked it's wi-fi signal a couple times.
Thanks for checking in, and you help!!! I'll continue to monitor it.

I looked at that last night and was totally lost.
I had been having a similar issue on a nearly identical machine, however, most of the time my MBP wouldn't recover and would require a hard reset. A couple of weeks ago I turned off hardware acceleration within my browser (Chrome) and haven't had a single freeze event since. It does sound like your issue is a little different than what I had been experiencing, but if you haven't tried adjusting your WebGL settings it would probably be a worthwhile experiment.
This problem is look like a CPU VRM problem.
I have detected this problem many times on rMBP 15inch models with one GPU and several times on 13 inch rMBP.
It is possible to fix it, if you have good soldering skills.

All A1398 models without second GPU have problem with processor power. I have fixed about 10 laptops with similar issue.
So is this a PSU issue? I've had desktop PSUs that degraded over time so I'd get random crashes and I just replaced the PSU with a higher capacity model.
Don’t mean to revive dead thread - I tested my 15 inch 2015 dual graphics MacBook Pro and no such issue occur - I do more testing to see. Vladislavus, привіт ! So you think this problem on only 15 inch single desiccated video(Intel iris) ?
