I needed my Macbook drive replaced, and my friend's completely dead Macbook drive replaced. I spoke to about 8 people who had various price ranges for the drives and I learned a lot of information in regards to the correct drives needed.
On Homestar I had several responses in regards to an in-home service and I chose to go with Adam after he called me and sounded caring and professional.
We agreed that he would buy the drives and the extra RAM for my friend's computer. However, it took almost 30 days for the drives to arrive and therefore Adam to show up at our condo. Once at our place, he knew what he was doing and installed both drives, cloned and upgraded my friend's computer to High Sierra. However, he couldn't install the RAM because he said he brought the wrong kind of RAM for her computer. He cloned my drive, and was also supposed to upgrade my computer to Mojave. The process was taking a while so he took a break and went to the Bay to get some jewellery for his wife.
Things still were not finished with my computer, so he said he would be back the next day with the RAM, and to finish upgrading my computer. He even left his cloning stuff at our place.
The next day he didn't show up and I texted him. He said he had an emergency and couldn't come that whole weekend. I also had to work night shifts and for a whole week would not have been able to reschedule. After 10 days we made another appointment. This brought us to just after Valentine's day. Adam texted to confirm the next day appointment. On the day of the appointment, he did not show up. I texted him and he said had a family emergency...again!
At this point I decided not to continue using Adam. I had finished upgrading to Mojave myself. My friend also chose not to upgrade the RAM. I discussed payment for the drives and asked for receipts for the cost of the drives. Labour for what he had already done was priced at $150. However, Adam was only able to provide a receipt for one of the drives, and couldn't produce one for the other Macbook. He sent us various links to how much a drive for my friend's MacBook should cost, but for all we know he could have gotten the drive out of an old Macbook and put it in hers. Although he had brought the boxes for the drives, they had no price on them.
Long story short, Adam does know what he is doing, but is very unprofessional in how he goes about it.
