Macbook has been slow for years, till now no idea why
Not sure what to add to this. I've gone to the Apple Store countless times to run diagnostics, and the results show no problems every time. It might be just because my computer is old (slightly over three years as of now), but I don't think it should be comparable to a 2015 Macbook Pro:
EtreCheckPro also reported a low performance, although since I don't have the Power User package, it won't tell me what I can do.
The following is the report from EtreCheckPro, and I can't seem to find anything that could have caused it:
I have also run many antivirus checks on my computer, usually using BitDefender's free version, but it always shows no problems. (The report mentions CleanMyMac, but I use that mainly for cleaning junk instead of security. It also says I'm clean of malware, either way).
If I have to be honest, I'm probably just paranoid, but it'd still be much appreciated if anyone could find anything I might have missed in the report that could be related to the slow performance.
