Mac Mini Logic Boards

Is there something fragile about the logic board for a mid-2011 MacMini? I just had my second one die at age 8 and Apple no longer manufactures them. It is unusual for this to happen twice for the same model, isn't it? And, to top it off, is it true that Apple has insisted on writing the serial number of your machine on any new logic board that it has installed? But now that they no longer make them and this cannot be done by them, using a logic board not inscribed by Apple may cause problems further down the line.

Unless you've isolated from grid fluctuation, filtered power; and used automatic

switching power regulation (with backup power supply; has battery to run Mac)

then your Mac can be affected by many smaller incidents that may not set off

the gross level of a primitive 'surge protector' or power strip, among others.


I've two different vintage Mac mini here; both on, and allowed to sleep. Seldom

restart an older Late 2005 Mac Mini 1.5GHz (last PPC version) runs Leopard 10.5.8.


And newer, Late 2012 Mac Mini i7 2.3GHz quad-core (server) with dual 1TB HDDs

both drives partitioned 50% ~ and in three of four portions, each has one macOS.

Newest macOS 10.13.6, oldest Mac OS X 10.9.5(server), and in daily use 10.11.6.


Decided more than 20 years ago to put an end to failed models/brands of power

related hardware problems. Hadn't used 'surge protectors' for any more than their

multiple outlets; found some good plain multiple non-surge protection ones instead.


[These have been plugged into at least 1250W backup APC mini-tower power filtered

UPS automatic-regulating switching units ~ they need new batteries every few years.]


Do not advance purchase these, as they don't store well, and their sealed lead-acid

batteries are like produce; if not used + exercised, they go bad on the shelf unused.

No point in having new-old stock, here; and a worthless expired warranty to boot.


Several brands of these have been tried, settled for those I can buy in this region

because they weigh alot and spare batteries are less costly to ship than new units.


So APC was not my first choice; other brands had immediate hardware failures; or

had designs that required replacement of entire UPS unit. Sealed to end-user and

evidence of surge and switch-over to their internal batteries; with insufficient tech.


These can or should have a cable to control UPS (special USB cable) so the PC or

Mac has means to also control their function; Mac has its own software included.

Better UPS (uninterruptable backup power supplies) are costly in AK where I live.

And having a spare on hand, means little ~ when they go bad, spoil like old fruit.


I can ration the power from one APC branded unit, shut down manually and switch

off the power strips to additional accessories, so the one(s) can be finished in use

before their automated shut-off time (or power depletion) causes the UPS battery

to run dead; and I've had more than 100 macs, safe behind automatic UPS.


There is no reason to use a 'surge protector' no matter their claims or fakery that

may suggest they actually add value to your kit. These generally IMHO are false;

and far better to proactively have knowledge and spare more expense to protect

via battery backups with automatic power regulation, instead of trickery or fraud.


The APC brand model of first acquaintance totally failed; on first power surge..

Had a battery backup and automatic switching, that failed on first run. And their

warranty was useless; they did offer for me to pay to return their failed unit.


That meant I wasn't getting warranty a replacement. So I bought other brands

which were then available; however the few stores that had inventory of those

went out of business. In isolated states such as AK, costs more to do everything.


Do not trust in poorly designed surge strips; and low-time battery backup UPS;

those, most useless. Battery backup buys you time to safely shut down your Mac.


Good luck & happy computing!🌻|🤖
