UPDATE: Version 126.96.36.199 was just released and it should fix this memory leak issue. If you are still having trouble, please post your experience. It will be rolling out, but you should be able to get it by downloading and installing from the Spotify website.
I am having a problem with the Mac desktop app -- there is a memory leak. (taking up too much RAM)
On my Mac I have always left the Spotify app open for many days usually just a week and then I end up restarting Spotify. I have the Spotify app always open so that it's ready to play music when I want. I keep my Mac on all the time and I have never had any other mac app have a memory leak like this before. I do occasianlly restart my mac as well. I have been doing this for years and this is the first time I randomly get huge memory leaks with Spotify all the time. To fix I have to close the Spotify app and restart it. After I close Spotify, I can see the swap memory (stored on hard drive) being freed up. But the issue keeps coming back no matter how many Spotify app restarts or Mac restarts. 30-40 GB of memory swap gets used and takes up all my free storage. I thought maybe this was just a rare issue, but I have been having this problem since verison 1.0.88. Right now I am using verison 1.0.93 and I still have the same issue.
This problem makes my hard drive unusable and takes up all the free space. I have to constantly restart Spotify. I am also worried about the damage it could be doing to my hard drive writing so much data.
macOS Version: 10.14 (happened on 10.13 too)
Spotify Version: 1.0.93
The newest version of Spotify (1.0.96) should solve it. Make sure to have the app up-to-date, and reinstall if it didn't help.
We'll close this one, but if you're still experiencing this, make sure to create a new thread and we'll help out from there.
