APPLE has international warranty but not in MALAYSIA because there is no APPLE store here.... it is going thru authorized dealer/reseller... not sure is MACHINES or EPIC something .... so the warranty is claimable from those authorized dealer only.. and they are not APPLE, so the warranty is not same.

APPLE is 1 exchange 1 in US, but in malaysia, you send back to autho-dealer, you wait for next week.. they solve your issue, for e.g. change screen, battery...blablabla.... so it is not 1 to 1 exchange on the spot...

so i think if you buy from US, you can claim from APPLE SG ... coz SG has Apple store....

of coz.... i not sure coz i nv buy any Apple from US or SG or any other places except MY ... i might be wrong.
