r/LineageOS

Hello! As being tortured for 11 hours of repeating the process of working on the rooting(done) flashing, procrastinating, finding tutorials, realising that my phone is Samsung S21 so have to install unofficial version, realising that I'm in Mac OS and Odin is not available, I have made 3 significant achievements, rooting my phone (Yay!) wasting my 9 hours of my life and not able to form a sentence without another cup of cofee.

To start off, I am using Samsung S21+ 5G and have unlocked boot loader.

I have found this link after realising that lineage OS doesn't support S21.

which this youtube video helped me with until, I ran a problem with the Odin part(since I have Mac OS),

Then I learned about Heimdall!

But after going to the official website and downloading the application, and activating the .img it said that Heimdall was not supporting mac anymore in current version which means that it has been discontinued since 2017.

I know there are continuing versions but I can't find it.

So can anyone suggest me what I can do from now on?

It's running on my Redmi note 8 for a year and till now it's still operating so smoothly.

I have a oneplus 13 and want to install lineage os on it. I use visible and currently have an esim on my phone for my network. Will this still work after switching to LineageOS or will I need to switch providers and if so who does work? Also anything else I need to know or keep in mind while switching, I have the guide pulled up and plan on going through it step by step. Sorry if this has been answered but I couldn't find a clear answer for the esim thing, especially with my phone model.
