Shiny Absol from Colosseum PID issues

[Brandon8]

Hi there,
I hope this finds you well!
I just pulled up the database to load a Pokemon Colosseum Absol. Everything was legal until I made it shiny. I rerolled the PID several times but it kept giving me the same PID error. Does anyone know what I need to do to make it legal? I see sometimes a few different programs recommended but I noticed none  of the ones I've seen mentioned work on Mac. I'd greatly appreciate it if you could tell me what to alter.

Thanking you in advance,

Did you reroll with PID with PKHeX? In that case, it's illegal because.. it's illegal.

Try this (and keep in mind other stat/natures/etc must be changed and follow suit)
