Is there any place in San José where I can fix Macbook Air

You may find one in a region or country ~ likely 'independent

authorized' service who may import Apple products for resale.

• Apple - Find Locations | Location Selector

https://locate.apple.com/findlocations

• Costa Rica - Apple Locate

[You may wind-up searching (duckduckgo/google?) to see

if some otherwise regional business name has association

for product service you seek. Be careful where these appear

because they may not be valid or honest. I've looked.]

Where named 'country name' may be lacking, see Other where

either one or another may appear. The authorized independent

businesses, are likely in regions where official Apple isn't there.

Some in Central America may find honest AASP in neighbor

country with Apple experience+parcel ship for repair orders.
