Mac Consults like Geek Squad

Hi all: Our Macs are getting old (10 year mark or so), and I fear to transition to new OSX or 10 version that it is at now -- alone. I will need help with internet, printers, etc. I live in Boston area. Geek Squad is now owned by Best Buy and most of the franchises were limited to PCs as well as the instore units before the sale. Is there some sort of similar company that will do Mac upgrade or consultants that are trustworthy? I wish Apple store did referrals or had some sort of service besides AppleCare which is limited to 2 years, but this is not the case. Any suggestions will be welcome. Thank you for your assistance.
