iconservicesagent OS Mojave issue

I have 3 Macs:

  • Mac Pro (16GB RAM)
  • Mac Book Pro (16GB RAM)
  • Mac mini (8GB RAM)


Did a CLEAN install on all 3 machines of MacOS Mojave.

Both my Mac Pro & Mac Mini are hanging all the time (Beachball cursor)

When checking the Activity Monitor, the process name "iconservicesagent" is hogging up all the RAM, i kill the process, but it still comes up and eats up all the RAM and machine is rendered useless!

I read all the threads that I can find, dating back to 2014. A lot of people are having the same issue. I don't know if people are having the same issue for MacOS Mojave? I just want to KILL this process forever! Not for a short while.

Mac Pro, macOS Mojave (10.14)

I had this problem. After working on it for the better of two weeks, I cleared the "Icon Services caches" using Cocktail 12.2.


Click on the "Files" icon. For "Choose caches" choose User. Click on the Options button and sure that Icon Services caches is selected. Then click Clear.


It was taking a long time, so I went to bed. When I woke up, no more iconservicesagent problem.

Today I did a little experiment: Testing ISA with a new, clean image.


I created a new image on a USB connected HDD with old Mac Pro 2012, Mac OS X 10.6.8. and disk utility.


Empty image:


• 500GB

• encrypted with 128-Bit-AES

• case sensitiv

• journaled


After disk utility has finished and I have plugged the hdd into USB-Port of my new Mac mini. Only plugged in the harddisk, didn't mount the images.


Only 5 seconds later ISA has detected the images and was going wild:


• CPU-Load > 100%

• toked all my RAM

• created a big swap-file

• overpowered all other processes.


No chance to eject the usb-hdd. No reaction.


So I had to use "force eject", but I takes more than a minute the finder will follow the command.


One second later ISA has become peaceful.


The current system macOS 10.14.5 Mojave still contains disk utility with the command "new image" and also the option "encryptions" and so on.



May be I'll do an other experiment next week...

I gave up on Mojave. For my purposes, it's a waste of time. You can't make a pony out of a pig. ISA won't stop messing with my time and my files. My iMac hums along just fine with High Sierra.


Your experience with ISA is similar to mine. Thanks for your post.


My whole ordeal did have a positive ending, however. Because I did try the Catalina beta, I found how much I use 32 bit apps and what I'd have to do when I eventually upgrade to Catalina. It means that I'll have to spend money moving away from 32 bit Aperture, which is an app that I love, and will have to deal with, IMO, an inferior and expensive substitute that likely will demand that I make monthly rental payments. I hate that stuff. But that's a few months from now.

I never used Aperture so can’t compare. But Luminar is a full photo editor whether used standalone or as a Photos Extension. There’s an article I read by one of the Apple Photos developers that describes the way extensions interact with Photos to decide which edit timeline to preserve so Photos can always restore the original. I’ve run into various situations where I can’t go back in the edit timeline because I overwrote it with Photos or Luminar. Try to find that article, it was very helpful.


i have thousands of RAW photos I haven’t edited yet, but there’s even more hoops to jump through to insure a RAW photo isn’t converted to JPEG then TIFF, thus ruining the quality. Again, try to find that article.

Dear friends RickKarrer and iPille,

unfortunately now the lines of the system code are millions of millions; devices and operating systems have increased (macOS, iOS, tvOS, watchOS and now iPadOS) and perfect results will be difficult to achieve.

I suggest to upgrade to macOS 10.15 Catalina. I've already updated, like Beta Tester and I'm very happy to have done it.

OT:

However, you're right in part, as some malfunctions are serious if they belong to basic functions, such as Finder.

So! Eg, I have sent a lot of feedback to Apple to improve the horrendous appearance of the Mail.app Preferences panels that are no longer resizable and therefore, for example, truncates the names of the many custom Accounts I use and so on...

I'm also trying to make Apple understand that it can't have a serious Operating System without the chance for the User to choosing a background image of the Lookscreen, different from the Desktop wallpaper! In many cases, in fact, the only choice that MacOS allow, let the profiling of the User!!!... For example, in a Mac leaved in Stop mode into a Library, a School, University and College, at Work, etc., if the owner has left the device some moment (eg. to go to the bathroom), just touch a key of the Mac and even if the password is requested appears, however everyone can see the active wallpaper at that time and could be a very personal image. An operating system must be robust because it is not a toy and even Winzozz (ehm... Windows) allows you to have a different screen image.
