High Sierra macOS freezing and stops

The sudo command should be used with caution.

The purge command remains somewhat controversial and best reserved for developers and fairly advanced users. For more info see this link:

the sudo command does things at the root level that in a newbie's hands can be disasturous. Not always, but sudo needs to be a red flag that you must know exactly what it will do and that is is recommended by someone you can trust.

Sorry if you got this twice

HiSierra 10.13.1

I use Logic Pro X 10.3.2

I have 27-inch 3.4 Ghz I7

16GB of ram 1333 Mhz DDR3 ram

AMD Radeon HD 6970M 2 GB

Logic Pro crashes on launch and quit of logic

it says the sounds are all installed.

I finally got the Apple Loops working and a lot go plug ins re-insalled and updated

it still crashes and Alchemy's database of sounds is gone !

😮

I am having the same freezing issues as everyone else. I have a macbook air and mbp and both freeze at random times. I've tried to isolate the issue to certain applications but it's completely random. Most certainly a high sierra OS issue. If anyone has a fix, please share.

Yes, I restarted the computer ,restarted PRAM and tried some other things. Same problem. I upgraded 5 days ago from Mountain Lion 8.5 to the latest High Sierra, same goes for the Logic Pro X.I have late 2012 Mac-mini with 4 gigs memory and two 1TB drives and I had no problems at all before the upgrade. Also Logic sound stops during playback.

Restarting the computer fixes the problem only temporarily .

First ,thanks everybody for their input.

I Do have 13.2 and today I installed yet another High Sierra update. Same problems. Did reset ,PRAM reset etc.

No results. Maybe Woodoo or Antifreeze ? I'm out of ideas. Getting more memory will help my Logic Pro X( I hope) but that "Sound freeze all" syndrome mostly happens while watching Youtube. After few minutes ( sometimes just seconds) sound stops.Before that happens everything sounds good.

Thanks, I am familiar with the store and was lucky enough to watch the memory card install video before I upgraded and my computer went nuts. Do you think that it's a memory issue and not the operating system? Seems like tons of people have the same ( or similar) problem.

I have reset PRAM, rebooted, have 16 RAM. I just upgraded from 13.1 to 13.2. I'll see if that makes any difference. I get locked out at sign in screen. It will suddenly freeze up while I work. No music playing. The cursor will not respond w trackpad or mouse. I have to restart the computer to get back to what I was doing multiple times in a sitting.

Thanks again. It seems that today's update messed my sample rates ,bit depth as well as the buffer size. After adjusting them there are less pops . Almost none, talking Logic. As far as keeping Safari clean ,I always empty caches ,reset and so on. Getting into the Console and Activity monitor is way beyond my scope. I wouldn't know what to look for.

BTW. I tried the link you posted in the other reply, but wasn't able to open it.I'll try again later.

I'm unable to fully boot since a restart last evening: I had no noticeable problem with High Sierra until yesterday, Dec. 7, when I installed the 10.13.2 "Combo" update. After an hour or so, my Late-2013 iMac exhibited several of the problems described in this thread and related (High Sierra) freezing threads.

The two symptoms of uncharacteristically slow response (beachball) to any action and never-before crackled/fading sound through headphones occurred while I had Adobe Lightroom minimized, was listening to a hard-disk-stored symphony via iTunes, composing an email in Mail, and occasionally viewing a 7-MB JPEG in Preview. Naturally, I realized that I was taxing the DRAM of my modest (8-GB) iMac, so I began to save work and close down all programs to just one or two -- to finish my email and then get back to other things later.

Such a routine has worked in past years. Time Machine was running also, and I postponed that backup, a complete one, to reduce memory load. After closing everything, I ran Disk Utility repair, with the HD and two USB storage HDs all finishing "OK." I then manually restarted, but probably did not need to (it's an old habit).

The system never has allowed a full reboot since then; that is, the login screen never appears (such as overnight, last night): I cannot boot in Safe mode, but I did reset the SMC and NVRAM. I can boot in Recovery mode and was prepared to Restore from Time Machine -- this all transpired before I discovered these threads, which I'm reading on my laptop PC.

Upon my attempt to restore using Time Machine and after entering my password to do so, I received the following alert: "There was a problem connecting to the server '[my name]-AirPort-Time-Capsule.local.'." Contact your system administrator for more information."

I am the only user/administrator and I'm on my home Wi-Fi network, by myself. So, I'm stuck.

Well, my wedges have always happened while I was actively using my MacBook Pro and have never happened when it was idle or sleeping. So, once again, my troubleshooting app says this is not related to why and when High Sierra wedges. I had too many issues during Beta testing to go back to Beta so I'll wait for Apple to release it in Production before I upgrade.

@dianeoforegon - thanks for that information, but after reading that I wouldn't DARE attempt a downgrade. LOL Having my mouse freeze every 15 minutes isn't that bad - in fact it reminds me of a Microsoft Windows system (pretty normal stuff for them).

In the future, always make a clone backup. This makes reverting easier. You boot from the clone, erase the internal drive and clone back.

I also suggest that you do not upgrade to a new system until it has matured. With the yearly updates, you can wait and upgrade every two years so you are covered with security updates or wait until the macOS completes it's cycle then update. ALWAYS make a clone backup first.

@dianeoforegon - Good to know - that I can wait to upgrade while still getting security updates! (at least for a year or two - not bad really)

I don't know if I actually made a "clone" backup - but I did backup using Time Machine before installing High Sierra (just incase something very bad occurred during the upgrade). However, being that Time Machine lacks the ability to back up Safari and Mail passwords (unless you use iCloud <-- that's what Apple told me (so lame)) - I lost some confidence in relying on Time Machine for backups. Although, I am continuing to use Time Machine for daily backups.

Also, I only upgraded to High Sierra because I was getting banners pestering me to do so. I had no idea High Sierra was experimental - I wouldn't have bothered had I known - since I'm not on the payroll for developers. In fact, all this sort of nonsense COSTS me more money. So, in addition to losing confidence with Time Machine - some trust has been eroded with updates.

But, macOS is still better than Microsoft Windows (for now anyway). I'd switch to Linux before going back to Windows though.

My MacBook Pro upgraded to 10.13.2 yesterday (must have done it automatically because I certainly did not tell it to run an upgrade; first time that has happened. I hope this problem will not recur. I would certainly not consider downgrading.
