the theoretical maximum for Linux is currently 128 TiB. However, this discussion is moot because AFAIK none of the current chipsets (nor the CPUs themselves) support this maximum theoretical amount of RAM - including the Intel processors in Macbooks.
And quite frankly I think you will at the very least change your Macbook several times before you are even offered that amount of RAM in any real life shop ;)
