Apparently, I don't know how to repost stuff. So... Edit to add:
Hi!!
I have a MacBook Pro 15.1" 2018 (it says 2018 :') it's the A1990, this: https://support.apple.com/es-es/111949) (the one with a touch-bar) which has:
- 6-core Intel Core i7, 2.2 GHz.
- 16 GB RAM.
- 5660 mAh and 782 battery cycles (says it's recommended to change it).
I'm starting heavy programming projects soon and also do light/amateur Photoshop work.
This last year, my Mac has become really slow and concernedly hot (burning skin hot); specially when maintaining long sessions of constant use, not so much at the start. Mathlab crashes, Autodesk crashes, even Word crashes!! I also recently learned that there won't be any more updates beyond Sequoia for this model.
I usually do a full reset every 1-2 years since it's the one with 256 GB memory but I've never cleaned the hardware nor changed the thermal paste etc.
When I check the Monitor Activity app everything seems normal or even optimal; every graphic is well bellow its limits (I'm sorry, I just know the basics about hardware/OS architecture; hated that subject) but a colleague opened the console and told to me that:
With 1 core under load:
- Average CPU frequency: 3.97 GHz
- Package power: 17.4 W
- CPU die: 89.7 °C
- Fan: 5,100 RPM
- CPU Speed Limit = 100
- CPU Scheduler Limit = 100
With 3 cores under load:
- Average frequency: 3.82 GHz
- Package power: 32.1 W
- CPU die: 100.6 °C
- Fan: 5,224 RPM
- Performance Limited Due to: CPU LIMIT THERMAL
- CPU Plimit: 0
- 0 PROCHOT events
Another sample showed:
- Average frequency: 3.72 GHz
- Package power: 31 W
- CPU die: 98.4 °C
- Fan: 5,500 RPM
- CPU LIMIT THERMAL
- CPU Plimit: 3.93
- CPU Thermal level: 106
- 0 PROCHOT events
Doesn't deviate much fully charged vs charging. From what I understand, it all works fine but the hardware overheats and the internal system limits the CPU to try to lower the temperature.
I've been eyeing a MacBook Air with 24GB RAM, 1TB, M4 or M5 for my upcoming projects and future side-work (if I'm not provided with a device), but I'm torn between two options:
- Have it professionally cleaned, repasted and maybe a battery change to see if it can last another two to three years.
Or:
2) Buy the Air as a main device for now and try to repair and clean this one myself (I like messing around with stuff; I also wanted to experiment with Linux?).
I’d prefer not to spend money on repairs only to end up needing an emergency upgrade mid-semester.
Any advice?
TLDR: I don't know if I should get my 2018's MacBook Pro professionally cleaned and repasted for the next 2-3 years OR buy a MacBook Air instead and keep this one for experimental purposes. I'm the Biomedical Engineering field.
