Extremely high memory usage in MacOS

Hey, I got the same problem in my MacBook Air (M1).

Hello!
I have a Mackbook Pro 16' with 16G RAM.
My Zotero frequently occupies a large proportion of my memory.
And it responds slowly. Other apps do not appear like that.
I guess there is something wrong with Zotero's memory usage.
(though I think Zotero is the best academic tool I ever use.)

Hi,
just wanted to confirm high memory usage on my M1 MacBook Pro 16' w/ 32GB RAM.

Working in one 4 page PDF without any other tabs open, RAM spikes up to 3GB. I can see sharp spikes when zooming in and out. It normalizes at around 2GB after some idle time.

1. How much memory does Zotero use?
2. How many PDFs are open?
3. Does this happen with all PDF files?

Zotero uses 3.11G memory when opening 4 PDFs, and I 'm not sure if it happens with all PDF files, but my computer is constantly reporting my system is out of application memory everyday I use Zotero to write essay.

when I open 2 PDFs, Zotero uses 4.17G also reporting my system out of memory.

1) And if you close those two PDFs, how much does the memory usage drop after waiting for a bit?
2) Are those PDFs scanned papers?
3) What is the size of those PDFs, and how many pages do they have?

ponyma

Zotero uses 2G memory if I close two PDFs and restart, the PDF is 970+kB and 17 pages.
Now, Zotero uses 2.38G once I open 1 PDF.

I restart my macbook to free up memory, and Zotero uses 700+mb without opening any PDF.

@ponyma Also you can try Troubleshooting Mode (Help → "Restart in Troubleshooting Mode…”) that disables all third-party plugins, to see if there is any difference.
