PT freezing every 5 seconds, for 2 seconds
 

This is weird. I use PT every day and this is totally new.

Every 5 seconds PT will freeze for 2 seconds. I mean, although it will carry on playing, the cursor line will stop flashing, and sometimes I'll get the beachball, and no buttons or anything will register or work. And if I hover in the menus, they freeze and stop working too. If I click around in those 2 seconds during the freeze, it's like it stores up each action, and does them in quick succession when it comes back.

I have changed NOTHING on my system. I've tried projects on different drives, still the same. All other software runs fine.

I do mostly editing and mixing and currently my system is completely unuseable.

Any ideas?...

I'm running PT 2019.12.0, on a MBP with High Sierra 10.13.6, 16GB RAM, 2.7ghz i7. Focusrite Clarett 8pre USB interface.

Just got this, too. Exactly as you describe. PT GUI freezes up completely every few seconds like clockwork. Very annoying.

Mac Pro 2013, 10.14.6, PT 2020.5.

I installed a Mojave security update last night. Wondering if that caused it.

This started happening to me, too. Was working last night, now... lag and stall lag and stall.
Does Pro Tools do some backdoor install? I thought it was all manual.
I installed 2020.5 a couple of days ago, but was fine until this morning. On Mojave for months.

Same, started today a few days after 2020.5 update
I'm on Mac OS X 10.13.6
Gonna try to roll back to 2020.3 I guess?

i've got the same problem…

i'm on Mac OS X 10.13.6 and everything was working fine yesterday… same sessions and all.

i was using PT 2019.10 and encountered these playback problems just today, so i switched to 2020.5 an hour ago, hoping it would be better, but to no avail.

i disabled auto-save, played with buffer sizes etc… no change.

Same thing here, 2020.5, 10.14.6

Holy Ghost?

Please everybody deactivate network connections, I think it’s an iLok problem…

Re: PT freezing every 5 seconds, for 2 seconds
 

yeah, it might have been an issue regarding authorizations… at one point i couldn't use EQIII and the other bundled plugins, but all the other plugs still worked.

but: my system seems to be running smoothly again…

I'm doing a Time Machine restore of my boot drive before the latest Mojave security update. According to Time Machine, my system was 10.14.6 (18G4032) before the update, and 10.14.6 (18G5033) after. But I'm not sure if this is actually the problem.

How many of you installed the latest security update?

Re: PT freezing every 5 seconds, for 2 seconds
 

yes, installed the security update, but I did that two days ago and this behavior just started today!
