I have been a Linux user for four years. Recently, I have been using macOS and I see it has very efficient memory management compared to Linux.
For example, here is a description of the documents/apps I have open on a Mac Mini i5 1.4 GHz 8GB RAM 500 GB HDD @ 5400 RPM:
- 40 pdfs
- 12 Safari tabs
- QuickTime video
- Sublime Text
With these open the Mac showed 5.91 GB of RAM used.
My question is: What's different about the Mac that on Linux I can't even open half the apps with a machine with the same amount of memory and HD?
