Big Sur with 4Gb RAM
In early February 2021 I bought a used MacBook Air 13" (early 2014) with macOS Big Sur already installed and I've been using it ever since then. About 3 weeks ago I started getting messages saying that my memory was low, so I should close some apps. I wonder how serious this is and if it's going to get worse in the near future. How should I manage my applications to stay within 4Gb? Can anyone tell me about some things that are impossible to do on my Mac?
I'd like to create some graphics on my Mac, but so far I haven't found any graphics programs that inspire me. Can anyone suggest some graphics programs which are for creating artwork, instead of just editing pics?
The Software I've installed and have been running includes Xcode, Swift Playgrounds, Keynote, Pages, Logic X Pro, Spotify, Kodi, and The Sims 4: Digital Deluxe Edition. Out of all these, it was obvious that The Sims 4: Digital Deluxe Edition took the longest to download and Origin/EA said they thought it was a 15Gb file. I have discovered Activity Monitor and put it on my Dock.
The official Apple line is that it's not possible to upgrade the RAM from 4Gb because it's soldered in. The installation of 8Gb RAM was supposed to be carried out whenever this MacBook Air was bought as new or never. I checked online to see exactly what would be involved in upgrading the RAM, then I found a video showing that the RAM chips look nothing like I've seen before, but quite like the keys on the built in keyboard and the type of desoldering and soldering is like nothing I've seen before either. You can see how it's done on a mid 2012 MacBook Air by clicking on the following link https://www.youtube.com/watch?v=yjFAr5nM4YU which has commentary in Chinese, but you can get English subtitles.
Of course, I mentioned above that macOS Big Sur was already installed on this 4Gb MacBook Air when I got it. Is it actually possible for me to do a fresh installation of macOS Big Sur on this Mac if I needed to, or wouldn't that be possible? I've just read on these forums that 4Gb RAM is insufficient to install Big Sur!
I certainly can't afford to buy a new MacBook Air or Pro, so I wonder what I can do to get my hands on another MacBook with what seems to be the minimum 8Gb RAM? It would obviously be second hand, and I'm not sure if I should get one that can run Big Sur, or just be happy with Catalina.
