I am planning on running the game on my mac, but the timer suggested in the rules seems to be windows only. Is it alright if I submit times with real-time, or is there another way to record with portal time?
I don't know what you can and can't open on a mac, but I know you can retime demos after your run using this tool: https://www.dropbox.com/s/wnu2we07wtok0vt/Portal2DemoTimer.exe
Alternatively, you can manually go through all of your demos and add up the times.
You can also submit runs without game time, but I think you can't get a better rank than 105th if you choose to do so.
Try WINE (WINE Is Not an Emulator) - www.winehq.org If you can't be asked to use Terminal, you can just get PlayOnMac, which is a precompiled version of WINE. www.playonmac.com
From now on, for top 50 times, both partners must submit their demos. As such, it will also be required for to submit any .vpks that are used during the runs. If you have any questions, you can join our discord @ discord.gg/p2sr or you can create a forum post here.
