Mac-Mini on APC BE750G UPS ?

Is anyone successfully using the referenced UPS (or similar non-pure sine wave model) with a Mac-Mini ? In my research I am seeing warnings about using iMacs with these "stepped-sine" UPS devices, and calls for using a pure-sine wave device. Do I need to worry about the pure-sine vs. stepped-sine issue with a Mac Mini ? I can tolerate some buzzing during power outages - my main goal is to ride out momentary power interruptions, and to have a proper system shut down for the Mac-Mini for longer than momentary power interruptions. (I realized after last night's 5 second power interruption that corrupted my iPhoto database that I need to take precautions ....).

I am not an expert in electrics but I believe this concern is out of date. Most cheaper UPSs will be stepped sine, I have been using the UK version of this model for a couple of years with no problem with some NAS servers.
I maybe wrong but I seem to vaguely recall that this was more of an issue with old style power transformers made from lots of laminated layers of metal. The 'steps' would eventually cause the layers to delaminate. Most modern transformers no longer use this design.

One APC UPS power supply to two Mac Mini via one USB control cable

Is it possible to use one APC UPS to control two Mac Mini to shut down when on UPS? The APC unit only has one USB control cable.

I wouldn't buy a PSU today for a high-performance system for any reason unless all of the voltage rails were separately supplied. AFAIK, only the Antec TruePower series and the PC Power & Cooling psu's can make that claim. Everyone else splits between the 5v and 3v rails, it seems to me--ie, with shared voltage rails the problem can be that when either the 3v or 5v rail demands more power then power is leeched from the shared rail to compensate. If devices on the shared rail need the power, though, then the voltage dip can cause problems with the devices on that rail and system instability (BSOD, etc.) can result. When all of your rails are powered seperately, though, all you have to consider is buying the psu that supplies the maximum you anticipate needing for each rail (with some headroom of course) and you eliminate the shared-rail power dip (a fairly common, often misdiagnosed problem) as a potential problem in your system.
No question PCP&C makes the best psu's money can buy, but I opted for the Antec True-Power 550 True Control instead simply because I can buy two TP550's for the price of one equivalent PCP&C cpu, and the TP 550 offers a few bells and whistles not offered by PCP&C (such as the intake fan which helps cool the TP 550's innards and improves its efficiency.) All psu's lose efficiency the higher their internal temps go, but of them all the PCP&C psus are the least affected by efficiency loss generated by rising operating temperatures--which is probably why they don't need a separate intake cooling fan like the TP 550. But the TP 550 has the intake fan nonetheless and is 1/2 the price of the PCP&C psu, and if memory serves the Antec fans are a good deal more quiet than the single fan used by PCP&C. So it's just a matter of studying the specs and the prices and choosing the one you want. But I'd constrain myself to these two brands because neither shares voltage rails internally.

UPS is no longer working with my Mac mini

My street has a lot of power outages, so I've used UPS units successfully for years with a series of Mac minis. Recently, my mini has shut down instantly on each of the last four power outages, rather than keeping going on battery power as it's supposed to. I bought a new battery, but then the old battery also tested okay. Today, (using the new battery) the lights stayed on on all the peripherals that were running off the UPS battery, but the computer shut down instantly. The APC phone support tech raised the issue of some computers needing pure sine wave UPS, but all the forum discussions on pure sine wave here say to ignore that.
How do I diagnose this problem?

It has to be the UPS since the MIni is sensing that power is lost to the computer when AC power is lost to the UPS. Yes, some users have had problems with APC UPS.
You UPS is old and has been discontinued.

Mavericks on my late 2013 Mac Mini (8gb RAM) does not recognize my APC650CI UPS as a UPS

I have a late 2013 model Mac Mini running Macvericks.
I just bought a an APC Back-UPS XS 650CI for it (I have 3 other Back-UPS 650CI for other systems - Windows 7 and 2x Netgear NAS setups).
In the Energy Saver panel of System Preferences the Back-UPS 650CI is not recognized, but it IS correctly listed in the USB section of System Profiler.
I have tried other UPS monitor programs: PowerSave UPS does NOT recognize it, but apscupsd DOES recognize it.
The Netgear ReadyNAs DOES recognize the new unit (I tried swapping the two Back-UPS XS 650CI's around)
I have reset the UPS - still not recognized.
I have tried on of the other Back-UPS XS 650CI's that I have around - not recocognised.
I have reset the Mac's Pram - still not recognized
I have reset the Mac's SMC - still not recognized
I have reset the com.apple.PowerManagement.plist - still not recognized
My ancient Macmini1.1/Intel Core Duo DOES recognize the Back-UPS 650CI in the Energy Saver panel of System Preferences.
Thanks for your help
Andrew

Answering myself
Had long conversations with APC/Schneider (quite helpful once you get past the drones)
They weren't aware of the problem but it does seem that Apple have removed/omitted the code that used to recognize the APC Back-UPS XS650CI at some point after Snow Leopard - Lord knows why. This despite the fact that it is correctly listed in the USB section of System Profiler.
The only solutions that I can see is either for APC/Schneider to get Apple to reinstate the relevant code (unlikely) and/or for APC/Schneider to issue an updated version of PowerChute for Mac (long overdue), which is possible but don't hold your breath.
I bought the (rather expensive) PowerSaveUPS app from the Apple Store but that doesn't work either (http://www.powersaveups.co.uk/) - I've emailed them to grumble but no reply yet.
In the meantime best bet is to use apcupsd for Mac - it isn't ideal but it works - RTFM.
The latest iteration is available on http://sourceforge.net/projects/apcupsd/files/osx-binaries%20-%20Stable/3.14.11/
Cheers!

Xserve G4 - Mac OS 10.3.9 Server - Possible APC Smart-UPS 1500 Problem

Hi
I have been receiving email "A problem has been detected on this server" from a clients Xserve G4 via the Server Monitor application. On logging on remotely there are no issues displayed under the Server Monitor or its log. On checking the Console Logs and more specifically the "hwmond.log" I see the following...
Wed Jan 23 12:18:23 GMT 2008 - We are now running on battery power.
Wed Jan 23 12:18:25 GMT 2008 - email has been sent
Wed Jan 23 12:18:28 GMT 2008 - We are now running on AC power.
Wed Jan 23 12:18:31 GMT 2008 - email has been sent
So basically the Xserve switched from AC power to the battery power and back to AC Power within a 5 second instance.
The bizarre thing is that if I check back through the previous archived "hwmond.log" logs, the logs rotate once a week, I see the same AC power/battery powers instance every 2 weeks at exactly the same day and time. An example of this is as follow...
Wed Jan 23 12:18:23 GMT 2008 - We are now running on battery power.
Wed Jan 23 12:18:25 GMT 2008 - email has been sent
Wed Jan 23 12:18:28 GMT 2008 - We are now running on AC power.
Wed Jan 23 12:18:31 GMT 2008 - email has been sent
Wed Jan 9 12:18:33 GMT 2008 - We are now running on battery power.
Wed Jan 9 12:18:35 GMT 2008 - email has been sent
Wed Jan 9 12:18:43 GMT 2008 - We are now running on AC power.
Wed Jan 9 12:18:46 GMT 2008 - email has been sent
Wed Dec 26 12:18:53 GMT 2007 - We are now running on battery power.
Wed Dec 26 12:18:55 GMT 2007 - email has been sent
Wed Dec 26 12:18:58 GMT 2007 - We are now running on AC power.
Wed Dec 26 12:19:02 GMT 2007 - email has been sent
The Xserve G4 is connect to a APC Smart-UPS 1500 via USB.
Does anybody know what may be causing this bizarre pattern of events. Any suggestions would be greatly appreciated.
Thanks in advance.

Okay found the answer in the pdf manual for the APC unit. Quote from the user manual...
Factory Default - Automatic Self-Test Every 14 days (336 hours)
User Selectable Choices - Every 7 days (168 hours), On Startup Only, No Self-Test
This function sets the inter-val at which the UPS will execute a self-test. Refer to your software manual for details.
The clients Xserve does not have APC's Powerchute software installed so I guess the Xserve/Mac OS Server's Server Monitor see's the automated test as something to report on and send out an email with no actual description of an error. Not sure what would happen if Powerchute was installed but at least I know what is going on now.

Why are there dozens of "web process" pop ups after wipe and load of 10.6.8 on Mac Mini by Genius Bar?

I just had my Mac Mini (early 2009) in at the Genius Bar as it was running very slow. They did a multi hour scan of the harddrive, etc. Did not find any hardware problems. They did a wipe and loaded 10.6.8 on the Mini. The Apple folks were great to work with. I picked it up today and and set it all up. Using Safari, I am now going through 6-12 "Web Process" with each and every web page I go to!! Safari is completely unusable in this fashion. Can this be changed or must I use a different web browser.

Good morning,
Not quite sure what you mean by 6/12 'web process' with every page I go to. The version 5.1.7 is correct for the Snow Leopard OS X.
Run a software update, just in case the geniuses didn't, and check if you or they have installed any Safari extentions. If so delete / disable them all and try again.
If Safari then shows signs of normality, reinstall the extentions one at a time until you find the one that is causing the problem.
Oh, and have you got 'Block pop up windows' checked in Safari menu?

Can i get a mac mini to boot by default when plugged in?

I am searching very long for a solution for this:
I want my mac mini to start by plugging in or an external switch even if there was no power failure. (which can be set in the energy saver preferences, box checked))
I found a thread which partly seems to concern this question, but i am not sure, may be some members here with more knowledge than me could help me, i would be very pleased:
https://discussions.apple.com/message/12111266#12111266
there i found the following:
"edited /usr/libexec/upsshutdown to send "shutdown -hu now" in both a normal shutdown or UPS shutdown. the -u simulates a dirty shutdown (see man shutdown) so when the UPS does powercycle it brings the Mac back online." posting by Glenn Gerrad
This seems to me as if i could use this change just to simulate dirty shut down indepenedent of having this APC UPS this thread is about, but i am not sure how to start this change for i am not used to work with the terminal and im afraid of ruining something because i am really unsure about the whole meaning of this thread. May be someone experienced can help me what to do?
Thank you !
(at the moment i am using hibernate, which works but i would prefer restart, because i eperienced some strange things which i could avoid by a clean start up.)

1.) Open Automator (Applications) and choose "Application" on startup.
2.) Find "Run AppleScript" in the list on the left side
3.) Drag & Drop that action to the right side
4.) In the text field of the script insert
do shell script "sudo shutdown -hu now" with administrator privileges
5.) Save that application to your hard drive and you can double click it.
6.) When running that application you have to enter your password, and it will shutdown the mac.
7.) You can hard code your password to the program with
do shell script "sudo shutdown -hu now" with administrator privileges password "yourpassword"
But the password isn't encrypted in the Shell Script!
Be aware: double clicking that application will immediately shut down the computer without asking for saving changed files - they'll be lost!

My Mac Mini won't turn on after being stored please help"

I stored my Mac mini for several months as I do every year but this time it won't turn on. Please help! It's an older version probably 2006-2007.

check out this discussion.
you should definitely get a decent UPS to protect your investment.
something like the APC Back-UPS ES 700 should suffice.

FYI - Just installed an APC Backup-UPS XS 1200 Model BX1200

This is a simple FYI... Read on if you have an interest in Backup-UPS systems for your Mac.
My experience with my neigborhood's power supply (or lack of it) this past week has made me think very hard about a UPS system. I did some research and ended up buying the APC Backup-UPS XS 1200 Model BX1200 to service my PM G5 Dual 2.5GHz system. This unit provides 1200VA and 780 watts.
Not only did I lose power abruptly several times this past week but have noticed at times when power supply AOK that my PM G5 would at times mysteriously shutdown for no good reason - but of course I suspect the power draw has caused my puny EnerGizer ER-HM450 UPS Power Protection device to give up on me. It has a VA rating of 450 and watts of 200 and supposedly a 2-8 mins of battery run time when power fails. This EnerGizer just wasn't doing the job for me.
My PM has 3 ext FW400 and FW800 devices and the PM case has two stock HDs and a 3x 500GB RAID-0 SwiftData 200 setup installed inside. Also have the Ultra 6800 graphics card along with 3x FW800 port PCI card and of course a 4-port FirmTek Card for the Swiftdata devices. I also have the Apple 23" Alu flat panel display along with iSight and powered USB hubs. On top of this I have a Brother B&W laser printer HL-5170DN, Cable modem and AirPort base station. Occasionaly I will also plug in my power supply for my 17" PB and various other things such as Mini DV camera, Cell phone charger and so on.
So as you can imagine the power draw can get quite high when all these devices demand their max power draw - especially the Brother laser printer.
The whole setup draws power from a single wall socket having 20amp circuit breaker. This same 20amp circuit also powers other wall sockets and over lights in my study/office where I house the computer.
So OK - I installed my new APC UPS unit and I have to say I'm very pleased with it. I now feel very much protected. It claims to provide me with some 30-40 mins of battery power after a power failure.
The nice thing about this device is that it's Mac friendly (I did not have to install any of the software that came with the APC device) and no sooner had I hooked up its data port to a USB port on the PM G5 the System Preferences... Energy Saver panel displayed a new UPS tab for setting up the various juicy things for the UPS system. It showed me the exact APC model I had just installed along with its UPS Battery Level percent (it showed 100% full). All very cool stuff.
I will take a look at the supplied APC software to see if some other goodies above what Apple provides is useful or not. This other software is called PowerChute and claims to have sophisticated Power Management - we will see. ;-))
Just thought others might find this report useful.
APC provides a useful web site for you to figure out and size the best APC unit to buy at http://www.apc.com/sizing
BTW - picked up this APC model at my local Staples store for $154 + tax.

I've been looking around online for more "user" opinions on the matter of the importance of true sine waves and approximated. I just got off the phone with an APC representative who explained to me the difference, but of course, since he worked for APC, he thought the difference you pay for in a Smart-UPS is worth it. He said the basic BackUPS are made so that the company can stay competitive.
I actually own a Smart-UPS 1500 - WAY overkill for my setup. I'm just running a PowerMac G5 and a 30" display. But when I was shopping for one, a friend convinced me that my equipment will last longer if I go with the Smart-UPS. But the load on that thing is at it's lowerest indicator and it kind of feels like a waste.
However, I know we have bad electricty at our apartment in Los Angeles, and often get brown outs, so maybe it's worth having.
Anyway, my question is, does anyone have any opinions on how much our Apple computers suffer (or do not suffer) from AVR (approximated voltage regulators)? Is it really worth the extra few hundred dollars getting a UPS that will deliver true sine wave?
I appreciate any insight.
Thanks,
Brian,.

My Mac Mini does not wake up from sleep. What to do?

After my brand new Mac Mini goes to sleep (by timer or manually), my Apple monitor usually (but not always) refuses to wake from sleep. Sometimes I can get the display to return, sometimes not, but in either case there is no subsequent response to my bluetooth mouse or keyboard, and my only choice is to shut down with the power button.
(I know there have been other question on similar issues, but most are old, and recent ones do not seem to have been answered. At this point, on Apple's advice, I am about to return the computer, but was wondering if anyone has solved a similar problem)
Mac Mini Mac OS X (10.4.6)

Yes, you would be surprised as to what low voltage (brownouts) can do. The problem is, most people don't realise how dumb the power supplies in our computers are and how variable their electrical supply is.
To illustrate this, we used to have a light plugged into a power board which was powered by a 5 step line conditioner (basically a UPS without a battery) and you be amazed as to how low the voltage gets. When the nominal voltage was between 196 and 240V (the line did nothing at this point) the light was constant enough although once it went below 196V the line conditioner kicked in topping the voltage up to 240V all of a sudden the light output doubled. On a bad evening this would be flicking up and down all night. Can you imagine what this would be doing to a computer?
My recommendation for you and everyone else would be to buy a UPS regardless. For the small amount a UPS costs they're well worth the investment.
My current favourite are the APC Back-UPS RS series for important/sensitive equipment although these do cost a little more and the 1000/1500VA units are quite big (so check the dimensions carefully). I have a 1000VA unit for my desk, another for my plasma TV and home cinema equipment and an 800VA for my ADSL line and server. Additionally I use the APC Back-UPS ES 500VA units (they have a much more convenient standard power plug for appliances rather than a D type plug) for less important/sensitive equipment like the fax machine, laser printer etc.

Mac Mini Server Shuts down every 14 days for no apparent reason.

Just before 8 AM every other saturday morning, I have a Mac Mini Server running 10.8.5 server that powers off. There is no indication of anything out of the ordinary happening prior to the shutdown. On restart the server continues to operate properly for another two weeks until it shuts down again. The only log entry I'm seeing that seems to indicate what might be going on is:
Dec 7 22:51:29 localhost kernel[0]: Previous Shutdown Cause: 3
This past weekend I attempted to get around the issue by having the system set to automatically turn on or wake at 11 AM, but that did not happen.
I've checked cron and launchd and nothing is scheduled around that time.
Any ideas?

Yes, a glitch with any less-interruptable power supply — they're never truely uninterruptable — could well trigger this outage.
If you're willing to run with grid power for two weeks plus a day, then cable the APC out of the path, and see if your uptime makes it to fifteen.
Probably much quicker and if you've got some off time where you can quiesce most of the activity on the Mac to allow it to crash hard with less risk to your data and your processing, then pull the input to the APC and see if the Mac crashes.
Various APC units run a self-test every two weeks, so a problem with the self-test or the switch-over or with he battery could well cause the reported problems. Could also be the quality of the power being generated (I'm running Smart-UPS units because of that) or the APC is overloaded, but I wouldn't expect that to occur on a particular schedule.
This reeks of the self-test or the power relay, or the battery.
Some semi-related discussions here, and probably elsewhere on the net.

Does the Mac mini mid-2010 have an active PFC power supply?

I'm about to buy a UPS unit to run my NAS, and I'd like to connect my Mac mini to it as well. Does the Mac mini mid-2010 model have an active PFC (power factor correction) PSU (power supply unit)?
I've read that if it does (as the Dell XPS series do), then one of the cheaper UPS units won't work because those typically have modified/simulated sine wave outputs (you'll only notice when the power is out and the UPS is feeding power from its battery). It would mean I'd have to buy one of the more expensive UPS units like APC Smart-UPS SC620 or CyberPower CP1000PFCLCD.
I can't seem to find any resources that explain this. Please?

FWIW, I use one of these:
http://www.cyberpowersystems.com/products/ups-systems/soho-ups/cp425slg.html?sel ectedTabId=overview&imageI=#tab-box
for my HTPC setup. I have a 2010 Mini with a couple of USB drives plugged
into it, my 42" Samsung LCD TV, cable modem, cable box, and an Airport Extreme
Base Station running off of the backup power ports (not my 5.1 receiver for obvious
power reasons). With all on, I get enough time to gracefully power down the Mini with
time to spare when power goes out. When not watching TV or listening to music,
the cable modem and AEBS can run a long time during a power outage.
I have had this setup for around 2 years and have had no ill effects on any of
the gear and I do periodically have everthing powered then yank the AC
cord to cycle the battery.

Uninterruptible power supply for mac mini server

can anyone recommend a good UPS for my mac mini server? i am a novice with these things so any advice appreciated: what i should look out for, will i need extra cables or can i just plug a uk plug directly into a ups, price v performance (there is a big range)
thanks

I would recommend you go with a small Smart-UPS, something like the APC Smart-UPS 750VA LCD. The 750 is a line interactive unit, offers avr boost/drop, surge protection and outputs a sine wave. This unit will provide you data center quality protection.
The Mac Mini consumes about 110W of power, so with the SMT750 you'd have over 35 minutes of run time on the unit alone. If you have routers and switches, it would reduce the run time a bit, but you can protect more equipment.
I wouldn't recommend going with the Back-UPS series of UPSs. They're not really designed for sensitive equipment and don't offer nearly as much protection as much the Smart-UPSs. We can't use them here at all because they don't get along with most Mac power supplies because they don't output a sine wave. Overall, they're just not as good as the Smart-UPSs.
We use the North American version here, in Europe you'd be looking for a SMT750I, "I" being the international edition.
We use a variety of these UPSs here at our office, they work like a charm.

Mac mini mid-2011 display issues 1920x1200 on a HDMI monitor?

Just puchased a mac mini and am challenged by the display settings. When I first powered it on using either a display port to HDMI or supplied hdmi to DVI (then the monitor's DVI to HDMI cable), the display is severly off center with issues seeing the system bar on top and icons on bottom. So, once I was able to get to the System Panel, I found that it configured itself to 1920x1200. I cannot get 1080p to center and 1080i has grainy text. Does this mean I need another apple accessory, ie display port to vga? Or is this an indicator that monitor and mac mini are incompatible? Or is this an indicator that the mac mini has a lemon card?
(NOTE: I am downloading system updates to see if there is a firmware update. Thanks

Mem - 4 GB
Graphics - Radeon 6630M
OS - OX Lion 10.7.3

Your monitor has a native pixel resolution of 1920x1200. There is no point in trying for 1080-p or -i.
I run two 1920x1200 monitors via HDMI (with passive cable adapters where necessary) and I use these choices:
...and they are both pixel-sharp, filling the screen, and yet menu bars totally visible!

Need Advice: New Intel Mac Mini Still In The Box

Hi!
Okay.. I know... I have several posts going here as I have several issues I am trying to solve rather simultaneously. Thanks for being patient with me.
I have my old 1.25 Ghz PowerPC Mac Mini running 10.4.11 and all was well and happy. Then Security Update 2007-009 happened and all went to ....well... you know and, yes, it was bad! Went to Apple, got it running of sorts as they re-installed the OS, but they used an old version of OS X. (10.4.7. Can you believe that?) This caused other problems. It continues to have all sorts of difficulties, as I have had to get applications to re-recognize that the computer is back up to 10.4.11. Currently, I am struggling with trying to get iTunes to access it's music folders on the external hard drives. Realized that I hadn't even gotten around to figuring out whether or not some of my other applications work, like some of the games and third party, etc.
The thing is I got a new Intel Mac Mini for Christmas and it's still in the box because as I suspected I need to get my old mac perfect again before I can even think about migrating stuff over to the new Mac. But.. here's the thing... it's starting to look pretty much like 2008 will come and go before I can get the old Mac ready enough to take the new Mac out of the box. This really is rather silly!
Now... I can't get the old Mac to see the music and it made me think. I have all of my iTunes music and iPhoto backed up on an external hard drive (I used Apple's "Back-up" software to do it) and in addition to this two complete copies of the iTunes music and iPhoto photos albums on two separate external hard drives. Should I just forget using migration assistant? Can I get my music and my photo albums into the new mac directly from the external hard drives?
Or...can I use "back up" to restore the music and photos into the new Mac?
I am starting to think that the best way to get my new Mac running is not risk it by attaching it to my old Mac. What do you think?
Thank you so much for any advice or experiences you can give. -Charlotte

I know that I am vacillating back and forth as to what to do. Thanks so much for being patient with me. All of your advice is really appreciated and I am at least closing in on deciding on my strategy. Probably will follow your first response advice, especially considering that some of the third party apps may not have updates to handle Leopard quite yet. Anyway... it's a good strategy since everything is on the externals anyway.
You can say that fine.
Ha ha ha.... yes, I've been messing around with computers since my parents bought our first Apple computer back in 1979. Just like you, I've never had a serious problem with any of the computers and we've had them all, running all sorts of things from the Original Apple and Apple IIc (which my parents still have and it still runs!) to the Commodore and all the Windows permeations and then on to the Macs running Jaguar, Panther and Tiger, probably because we've always been careful with the machines and what we install in them and how we update them. I have always kept my computers on UPS' and un-plug them when storms brew outside. As it is I am still using my eight year old Windows 98 computer, (for games mostly) and it still runs quicker than most peoples windows pcs and it's only a 740 Megahertz.
I haven't had to re-install anything, especially on this lovely little Mac Mini until now and wouldn't have in this situation, had I known more. I had taken the little Mac Mini in for a Procare "Tune-Up," only four days before the big up-date disaster. Not sure what they did to my mac in the tune-up but the guy gave me back the machine assuring me that the computer was perfect with no problems in answer to my asking "were they sure?" Even after the Genius Bar techs at the Apple Store re-installed the OS to fix the big problems it seems that no one ever thought to run verify disk. Had the Genius Bar techs at the time of the tune-up done this, or at least told me to do this, the last security update would not have wrecked so much havoc. It was only after I got the machine back from Apple that second time that I found that the directory had been corrupted when I ran disk verify. Actually it is amazing that I have had this little Mac Mini for so long and so not have had any problems on it that I would be able to go so long without having to know this really pretty important aspect of keeping one's mac in good running shape. I had been running maintenance scripts and permissions verify and repair and thought that was all there was to it. Silly! You know... that really is a testimony of how nice these little machines are.
Anyway... experience is a good teacher and I have learned so much it's actually been great! This stuff is pretty interesting.
Now... on to Leopard!
Thanks so much and you have a great New Year! -Charlotte
