Xcode and app submission

I know this gets asked to death but one more time won't hurt right.

so to submit an app you must use xcode 26. xcode 26.3 is supported on sequoia, sequoia is supported by oclp for any Mac basically 2010 or later.

so will I have any hurdles? , my flutter app is completed I just need to test in the sim, deploy and submit, (don't care if it takes 12 hours to build, it's a one and done) I'll sell the Mac a month later for the same as what I paid for it.

Am I missing anything?
