I can never book any appointments via the online page, in any of the Apple Store Genius Bars in Hong Kong. Can I just do a walk-in with my MacBook here?
I know in the US and Mexico, you can just drop by and if any of their tech guys are available, they will help you out.
My colleague did it once with his iPhone here in Hong Kong, but was declined, he eventually got his problem solved by paying an external technician.
Anyone with similar experience to share?
