Hi everyone, after almost 12 years, it's time to say goodbye to my Late 2011 Macbook Pro 13". I'm stuck with HighSierra (10.13) and not even Chrome or BraveBrowser release upgrades for 10.13 anymore. As far as I know, it's not a good idea to use and old OS but it's an even a worse idea to browse the internet with an outdated browser. However, technically the Macbook Pro 2011 is in perfect condition and still works flawlessly (after upgrading to 16GB RAM and 512 SSD a few years ago). Therefore I'm looking for solutions, without havnig to spend over $1499 for a new Macbook Pro My current plan would be to install Parallels Desktop 17 and run Windows. Windows will do the job just fine, because I have to concentrate on my master thesis for the next 6 to 12 months and won't need anything else except Microsoft Office and an internet browser. I am aiming for Parallels Desktop 17, because it's the last version, which is compatible with High Sierra, according to the official website of PD. **My question**: are there any security issues when running PD 17 on an outdated High Sierra? Or are there any other issues, which I should be aware of? My reddit and google searches couldn't help me find an exact answer so far. Thanks.
