Upgrading a CoreDuo mac to Lion.

[macspam]

How could I skip the processor verify in order to install the new Lion beta in a CoreDuo MacBook 1,1.

Hardware specs: 160 Gb., CoreDuo 2 Ghz, 2 Gb RAM.
Any help will be much appreciated!

By the way: I do not have another mac with a Core2Duo -or later- processor.

Thanks

You can't. Lion checks the CPU to make sure its 64bit.

Hi, thanks.
Maybe it is possible to make a firmware update. It is just to put a "2" between "Core" and "Duo"

Thanks! I agree, but I do not have a Core2Duo mac. I am the happy owner of a MacBook 1,1.

That link is about the Core Duo, not the Core 2 Duo. I would suspect that come release, it will no longer be possible.

You are right. However, it is also a "known issue". So, lets hope Apple make Lion a CoreDuo compatible OS.

there is two point for Lion GM:
1) install a Lion on a Core Duo Mac. This will be near impossible to have a really usable system, because some component (finder?) are 64 bits
2) better : install Lion after replacing the core duo processor by a core 2 duo which is pin compatible. This need remove some computer id checking in setup (or use target firewire mode from another mac), boot.efi and, pehaps, kernel
