Mac Mini i7 2.3Ghz with 16Gb ram locks up

My new Mac mini keeps on crashing but not completely as it seems to be the finder that is having problems. I can be running iTines and it will continue to respond and play music but when I try to shut down the mac just sits there with the busy icon twirling. I am then forced to hold the power button down to force a shut down. Thanks Mike

Hello, see how many of these you can answer...
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab of Activity Monitor, are there a lot of Pageouts?
Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Then move these files to the Desktop for now...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.

Yes, you can go up to the max of 16GB on your Mac Mini.

Just purchased a new mac mini 3GHz Intel Core i7, with 16GB ram version 10.10.1. With it i purchased a new wireless keyboard. All of a sudden I was not able to use the #1 key. I thought I had a defected newly purchased keyboard. I pulled out my older wireless keyboard, and the same thing happened. It must not be the keyboard if it happened to two different keyboards. I have a habit of restarting my computer, when things don't work, I find it helps, and sure enough, everything works. Today, it happened again. Does anyone know what is causing this to happen?

Screen flicker Mac Mini i5 2.3GHz 2011 ?

Hi people,
Does anybody else also experiences screen flicker on the Mac Mini i5 2.3GHz 2011 model, during startup from sleep-mode or a cold-boot in the morning?
I posted a video on YouTube, to visualize the problem (otherwise hard to imagine, perhaps):
http://www.youtube.com/watch?v=5sbAhjlfN_M
Room temperature is about 15 degrees Celsius (Europe, wintertime) and the problem exposes itself when the machine is powered up after a nights sleep, or during a cold boot in the morning, the screen flashes from like the same in the YT movie, but then with the grey background and Apple-logo on it, continuing until the working desktop appears and then flashes some few more times, until "warmed-up".
When the Mac has woke up during the day, room temperature about 23-25 degrees Celsius, the screen doesn't flicker at all, or at max. 1-2 times.
The main screen (on the YT movie) is connected through Thunderbolt with an original Apple-brand mini-DisplayPort to DVI convertor and the secondary screen through a (with the Mac Mini facilitated) HDMI -> DVI convertor.
The second screen always lags a little behind the main screen and the desktop appears when the main screen desktop has fully appeared, so no flickering on the second screen noticed, till so far.
Setup:
-Mac Mini i5 2.3GHz, model 2011 with a Kingston V+100 96GB SSD and 8GB Corsair RAM 1333MHz;
-Main screen: Thunderbolt -> DVI, Dell 2005 FPW 20" IPS-panel @1680x1050;
-Secondary screen: HDMI -> DVI, Dell 1704FPT 17" TN-panel @1280x1024.
A SMC-reset and PRAM-reset didn't help, contacted Apple-support which recommended to download the generic Thunderbolt-patch DL1451, which I later recognized in my Software-update list in MacOS, as already download in October 2011, named/tagged: Thunderbolt 1.1
The Mac is already running the latest firmware, EFI 1.4 (the machine is brand new, so expected no less then the latest to be honest.)
Next step I'm going to try is: switch the screens on HDMI <-> Thunderbolt (didn't try that yet.)
Never experienced this with my Mac Mini's 2009 before (had two of them, first the 2.0GHz and later the 2.26GHz- big Mac Mini fan overhere!), running the same setup (but then on Mini-DVI & Mini-DisplayPort.)
It really feels like the internals of the Mac Mini 2011 have to warm-up, before fully functional...the Apple specs give me an operating temperature of 10-35 degrees, I'm not living in a cave, neither I accidentally forgot to turn off the air-conditioning system after the summer ended, so what the hack?
Reminds at my childhood, the time we still used B/W television @my parents home with kathode/anode-tubes in it, they also needed some time to "warm-up" before presenting a stabile image ;-)

Did you find a solution? I have the same hardware and same problem. I dont connect via thunderbolt, just the DVI-cable supplied by Apple to my TFT monitor. But without any hardware changes or updates it started a few days ago.

13'' dual-core with 16gb ram vs 15'' quad-core 8gb ram -- ram vs cores?

Hello. I am at a point between choosing a 13'' dual-core i5 with 16gb ram vs the 15'' quad-core with 8gb ram - both retinas.
I will be using photoshop and illustrator while uploading/downloading large files constantly. After much headscratching I almost decided on the 13'' i5 because from my experience, RAM limitations is where I usually run into problems, and don't see the extra price of i7 worth it when it is still a dual-core. For the same price I can get a 15'' quad, but will be stuck with 8gb ram.
I don't care about the screen size, I have good eyes and the weigth trade-off makes this a non-issue.
I'm thinking about down the road, as either of these I'm sure will be fine solutions. I'm just wondering where does the edge really come in this case? Ram or processor / cores?
Thanks.

Thanks for your reply tjk, of course with 16gb on the 15'' for $200 more I'd have easier time, but in this case I am comparing a refurbished - the lowest 15'' 16gb I could find would cost $500 more, I just can't do it.
I should make clear that this particular comparison between 13''w/16 and 15''w/8, they are the same price (the 13 being new) - which is why I'm stuck.
To rephrase - for the same price - which will I regret less in 4 years?
As a side note, I can't believe I'm even thinking about paying this much money for something that is not upgradeable, but that's another discussion entirely.

You would need OS 10.8.x for mirroring. But no you can mirror your iPad to your mac mini See here for more information http://support.apple.com/kb/HT5404

Mac Mini Upgrade to Lion with USB: can't download Server Add On

I have a Mac Mini on Snow Leopard and I bought the Lion USB key to upgrade to Lion. I have a weak internet connection. Unfortunately, the first thing that happens when I insert the USB key and start the upgrade is that it needs to download the Server Add On. What is very bad is that it says to look on the App Store app to monitor the download but there is nothing happening here. My ADSL box shows no activity. Why do I have to download this? how many Mb is it? can I skip it somehow? If I cancel, it cancels the installation...
I am very disappointed and unhappy by this, I thought I would upgrade to Lion easily, especially after buying the USB key for 69 euros (I live in France).

The only solution I found is wipe the hard drive, install Lion then install the server part. I am not really interested in a drastic solution as this one which takes time and careful backup and is stressful.
At the very least, were I upgrading like you, I'd clone what I have to an external -- either bootable or in a disk image -- in case you need to roll back.
I've never upgraded any version of Server before, but that drastic measure I take all the time with major OS upgrades. And Snow Leopard to Lion is a major OS upgrade.
It's too bad that Apple doesn't make a straight Lion Server OS "bundle" available for purchase for the price of Lion client + server add on. That way you wouldn't have to do a two-step install to get to Lion Server. It certainly exists, I've downloaded it for my Mac Mini Server, which shipped with Lion Server, when I wanted to reinstall Lion Server.

Would VMWare ESX(i) run on on a W510 (i7 920 with 16gb ram)?

Hi all,
A tough question perhaps though perhaps something useful to know for quite some users:
Would VMWare ESX(i) run on on a W510 (i7 920 with 16gb ram)?
All thoughts and comments more than welcome!
Jochen

I see no clue why it wouldn't. I used to have ESXi installed on VMware Workstation on my W510 i7-920 with 16GB RAM. I have yet to find a spare hard drive to install ESXi on bare metal.

Mac Mini Server Airport Express with Server Firewall Settings

I posted this in the Server forum, but I've had no responses so far - so I'll try it here instead! Any help is appreciated...
I've got a new Mac Mini Server (mid 2010) with Snow Leopard Server v10.6 that I intend to use as a file server in the long term, and as my main computer replacing my old PC in the short term.
One of it's uses will be my iTunes server for my Airtunes network with two airport expresses.
When I disable the server firewall iTunes can connect to the airports with the check box in the 'multiple speakers' menu in iTunes. If I enable the firewall with the default settings of 'allow these ports' I cannot. I have used the Apple document on well known TCP and UDP ports to open for Apple software packages with particular attention to streaming audio / iTunes etc. Still doesn't allow the speakers to be selected in the 'multiple speakers' check box.
I also tried the 'allow all traffic' option for the firewall, again no connection to the remote speakers happened. If I turn off the firewall it all works fine. It seems that there are some ports that need to be open in order to establish the connection - I just don't know what they are.
Does anyone know of the appropriate ports to open? I tried searching the forums and I did try some of the suggestions for port 5000, 6000, 6001 etc but it doesn't make any difference!
Thanks in advance...

I found this works too. Though I came about this a slightly different way.
I moved over to Airfoil as Airtunes didn't work without the firewall and Airfoil did. I then had problems with Airfoil not reconnecting to the remote speakers when you cycled the power on them, I don't want all of my remote speakers powered all of the time. They were set to automatically connect, yet they refused connection a couple of times before connecting, which meant logging into the mini and reconnecting manually, which wasn't what I wanted to do. During an email conversation with Rogue Amoeba I sent them a debug logfile - they pin-pointed it as a connection denial with IPv6 addressing.
Once I had that info, I disabled IPv6 for my network adaptors and Airfoil worked and reconnected fine even when airport expresses are power cycled. I then tried Airtunes again and now the speakers can be connected. It's down to the first choice for connections is IPv6, if this is not available it's IPv4.
It's definitely a bug with the IP6FW control and link-local traffic.
Hope this helps.

Why does my new MacBook pro retina with 16gb ram keep randomly freezing

Hi ..
A new Macbook Pro should not randomly freeze.
You have 14 calendar days from the time your items are delivered to initiate a return as noted here.

Should I go for a 13" retina MBP with 16GB Ram and 2.8ghz dualcore or a 15" Base model with 8 GB Ram and 2.0ghz Quadcore?
