Apple slashing prices
I'd reckon that would be the only way Apple would stop a decline in sales. They marketed themselves into the fashion department, which is usually also tagged as "useless & expendable". When you're cash-strapped, flashy things suddenly aren't that important anymore; and you surely aren't going to buy a new iPhone/MacBook when you barely can pay your mortgage.
During economic recession, it's usually the "bargain prices" brands the one that actually keep having profits, as it is less probable to be put in the cost-cutting guillotine. Most of Apple's products, however, have a 10x cheaper equivalent, even if it is from some shoddy Chinese outfit.
