Does Mac have swap? If so, how does it allocate it by default?
- kzrdude 5y agoMy macos knowledge is dated (didn't use it seriously since 10.5), but it used to be a dynamically growing collection of swapfiles, usually covering all of the RAM (probably can't do that anymore).
- umed 5y agoMacOS Big Sur: recently implemented an algorithm that leaked and left it running for quite some time. Got notification that there is not enough RAM and suggestion to close some apps once size of swap grown up to 64GB (or it was size of RAM + swap, don't remember).
- Toutouxc 5y agoYes, macOS creates a series of 1 GB swapfiles on a special disk volume called "VM".
- vaylian 5y agoWhat does VM stand for?
- bufferoverflow 5y agoVirtual memory, guessing here.
