Does application memory mean you have run out of memory space on your computer? How can you add more application memory?

You'll get this message when your startup drive is very full.

MacOS will use some of this disc space for application memory when RAM space is low. When the system can't find sufficient drive space it will let you know with this warning.

You can mitigate this by keeping your drive space available - some say about 10%.

How's your memory pressure? If it's all green that's good; it's usually better if the green bar is low on the graph. As it sneaks upward, your pressure increases and when it get to red that's not so good.

Actually you need to restart at least once per week anyway. Restarting has a number of beneficial actions.

He means you have to leave about 10% totally unused at all times to allow the OS space to operate.

You regain disk space by deleting user data after copying it to an external drive or cloud storage. iCloud is not designed as cloud storage.

I'm running Monterey 12.0.1 on an iMac (Retina 5K, 27-inch, 2020) with 8 GB of memory and a 1 TB harddrive, 698 GB available, and still get this error message on occasion. The one I got this morning, I was running Music, Mail, and Chrome (3 tabs open). Running Activity Monitor now, the largest one is called "WindowServer" 1.46 GB. I've checked and my pointer color is set to default colors (as mentioned in another thread as a possible browser memory leak issue). Whenever I've encountered this in the past, I've rebooted the system and seem to be fine for a few weeks before it reappears.

How do you do that? How do you allot drive space?
