Apps on iMac Slow to Start Up
I'm looking for some suggestions here. I have an 2015 iMac 27" Retina 5k. It has 16GB of memory and a 1TB Fusion drive. SO I have plenty of horsepower.
The problem is at times I see some apps taking over a minute to start up. I can watch the icon bouncing in the dock for a long time before they start up. Apps such as Chrome, Word, Pages, etc.
I have tried looking at Activity Monitor while this is happening but I don't see anything causing this delay. There is plenty of free memory, plenty of storage, yet it can take quite a while for some things to start up.
I've run the various things like Disk Utility, EtreCheck, Clean My Mac, and the likes.
I'm wondering if by chance the Fusion drive could be an issue. I've contemplated getting at external SSD to see if that makes a difference, but wanted to put the question out here first to see if there are other ideas that people have that I could try.
Any ideas from anyone? Thanks in advance.
That's a good idea. Definitely I have a nightly clone, in fact several backups. I have booted up from the clone, but just to make sure it works. I can try that over several days and see if it gives any clue.
Just an update. I haven't forgotten about this. I just haven't had the time to test things out using my clone. I hope to try it over the weekend.
So I finally had a chance to run off my clone today. I was using Microsoft Word and Google Chrome as test cases. Each of these took 60-90 seconds to start up on the initial open. They were a little faster on subsequent opens probably because the app was loaded into memory. This is the same sort of timings I was seeing using the internal fusion drive. So perhaps I'm seeing normal behavior and I have been spoiled over the past few years with the ssd in my Macbook and Macbook Air.
So I guess my question is, has anyone else noticed startup times for apps in the 60-90 second range using a rotation drive? Perhaps I'm looking for a problem when there isn't one.
I launched Chrome first time in 25 seconds on my Late 2011 15" Macbook Pro with the original 750GB rotating hard disk.
Relaunch right after quitting Chrome happened in under 2 seconds.
I do not have MS-Word, so I cannot test that.
Have you used Onyx to do a more "full blooded" clean up? (I can't see it mentioned above) I'm not aware of the inner workings but all sorts of caches & linkages have to be exercised on app startup so forcing a rebuild of all of that could be helpful.
While I had not tried Onyx previously since I use things like Clean My Mac, etc, I decided to go ahead and run Onyx. I let it do its thing and then rebooted. When I tried Google Chrome, the icon bounced in the dock for 2 minutes before opening a browser window. I quit Chrome and started it again and it started within 5 seconds.
I then tried Microsoft Word and it took 40 seconds to open. Upon quitting it and opening it again it opened within 5 seconds.
I would expect since I have 16GB of memory there shouldn't be any thrashing and I don't see any. I just can't figure out what some of the apps are doing with the initial startup.
Any more thoughts?
I am contemplating a clean install when I get Catalina, if for no other reason, just to see if it makes any difference.
So I am cautiously optimistic. Here is what I have tried.
Graham, I switched to my TestUser account and tried to open Chrome. Of course it opened quickly (within 10 seconds). That got me wondering if that is because I had already opened Chrome my my normal account previously. SO I rebooted the computer, logged into the TestUser account and Chrome opened right up.
I then switched to my normal account and opened Chrome. Of course it opened within a few seconds. I tried that several times today and it opened normally.
Here is what I am thinking. I have been running Clean My Mac X (from Setapp) routinely, every week or so. By default it is cleaning out the system and user caches. I think whenever I was opening Chrome, Word or whatever, it was after running Clean My Mac so the caches were empty. So I may have been doing this to myself., which is usually the case. 🙂
I will keep watch over the next week with normal use and see what happens. I will also check the preferences or options with Clean My Mac X. There will times when I want to clean out the caches, and other times when I do not. Hopefully I have control over that. In either case, I will keep an eye on things and report back next week.
By the way, I don't see that same behavior on my MacBook Air, but that could be because it has an SSD and the iMac has the fusion drive.
Thanks for the suggestions Graham, and everyone else.
