Brilliant solution to overheating!

My 15" MacBook Pro was about a year old last summer and I signed up for a course to help me create apps for classroom use. One of the tasks forced me to download a piece of software and to use it to create a 'phone app. The software was very obviously not created for Mac and I was rather unhappy to be asked to add it to my lovely newish computer. I left the course when I found it just wasn't working, just about the flakiest piece of software I've ever used. I think it was called something like CreateApp or DesignApp, something like that. I didn't notice the connection but after that my Mac was just not behaving itself. After another six months my hubby suggested I buy another and I passed the old one on to someone who was still trying to use a ten year old Mac, thinking that it would be cheaper to get it fixed than to buy a new one.

I used migration assistant and found that my new 16" MacBook Pro was running hotter and hotter. I started up iStat menus and found it was mostly between 70° and 95° - the lower end of that range when it was just sleeping with no apps at all running. I came on here to try and find a solution. Enter another user called eaglecj, who prefaced their question about an overheating Mac with a really long system report by a programme called EtreCheck. I tried downloading the app myself and found that for a modest investment you could get it to provide the solution. It came up with reams of information but the best bit was advice to uninstall the nasty piece of software I had installed the previous year and forgotten.

Etrecheck took me to every piece of software in the bowels of my machine that had any connection with the installation and told me exactly how to remove it. I emptied the bin, restarted - and was amazed with the result. My temperature range was instantly down to 30° - 50° and this feels like a new machine.

I don't need help but I thought others might benefit from the tip!
