The smaller of Apple's MacBook Air laptops featuring dual microphones and 802.11ac Wi-Fi connectivity. Here are some tests I have when I ran Apple Hardware Test from original Tiger install disc. My issue is recurrent worsening inconsistent kernel panics. The Hardware Test hangs up at 35 seconds, while 'testing memory.' The first time I ran it I didn't realize it had hung up till I looked over the display after 3 or 4 minutes.
If you think your Mac may have a hardware issue, you can use Apple Diagnostics to help determine which hardware component might be at fault. Apple Diagnostics also suggests solutions and helps you contact Apple Support for assistance.
