I recently started using Apple’s Notes app for taking notes and storing temporary bits of text and URLs. I use Evernote for long-term storage of this sort of thing, but Notes is an easy to use tool for me to jot something down – or dictate it – on my iPhone, and have it available almost instantly on my Mac.
However, I’ve noticed that Notes is using a huge amount of RAM. Here’s what it is currently using on my Mac:
That’s 7.38 GB on a Mac with 16 GB RAM. You can also see that there is 7 GB of swap memory (virtual memory) being used.
This has something to do with networking. If I look in Activity Monitor, there are about 100 processes called Notes Networking, each of which is using between 8 and 9 MB RAM.
I have no idea why this is happening; this isn’t just a memory leak, but these are processes being spawned for some reason. And my Mac has not been running long; the last time I restarted it was less than two days ago.
The only solution is to quit Notes regularly and relaunch it.
