About this mac - Storage (multiple hard drives)
I have an issue with About this mac. I have a 27 inch 2019 5k iMac, 16GB Ram, Fusion Drive, 3.1 Ghz i5, 575X 4GB, running Catalina 10.15.2.
I have an externally connected 4TB Western Digital drive, connected by USB C.
I only use the fusion drive for apps and have 948GB of 1.03 TB free, so I've only used about 50GB on this drive.
On my second external drive I have my user folder and have 2.53 TB of 4TB free. Disk health on both is excellent with DriveDX.
When I open "About this mac" I notice a slow down. When I open activity monitor under Memory it shows the culprit as Books. I close the process Books (which does not appear as an open application in the dock) & leave activity monitor open but close about this mac. If I reopen "About this mac" and select storage, the process "Books" will open, but the app does not. This "books" process starts taking up ridiculous amounts of RAM.
When I look at "About this mac" it attributes way too much storage to the fusion drive, which only holds 50GB. My user information for TV (815.4GB) and Documents (125.67GB) etc which are physically held on the second drive are reflected as being on the Macintosh HD.
I'm not sure if they are related to my sluggish performance, but this feels slower than my 2010 i7 with SSD and 2TB HDD. Apps open slower (multiple bounces in the dock and videos on VLC stop playing (pause) while apps open, even when there are only minimal apps open.
Any help with this as to why it may be happening and what to do to resolve it would be great.
