Incredibly BAD airport performances on "unibody" Mac Mini

Hi everyone,
i've been experiencing very very very BAD wi-fi performances with my "unibody" Mac Mini.
The network connection is everything but reliable, it keeps disconnecting, the signal strength keeps jumping from 1 wave to full signal and viceversa. Networking is always extremely slow even if sometimes the speed rises up to the maximum allowed; I've been downloading at 750 KB/s using transmission and suddenly the speed drops to 4-6 KB/s..watching a vid on youtube is painful and everything goes very slow and with no reliability. Often the net stops working completely and i've to disable/enable the airport card from the menu bar to make it start working again.
I've the same network configuration on my 2008 pre-unibody MBP and it works smoothly, with no issues at all, sitting right next to the Mac Mini; i've tried to turn alternatively one of the 2 computers off to check their performance separately and the Mini is the only one giving me troubles showing a completely random network speed.
I didn't test the mac mini performances in a different room, but there's just one room between the Mini and the wi-fi router.
I'm sick of it, and i want to give it back to the Apple Store Online. If the problem is the distance it means that the new antenna is much worse than the older ones.
Anyone with the same issue? Should it just be a defective airport card?
Weirdo though, considering that sometimes it goes how it should.
Oh, my iphone connects smoothly to my network, even from the parking lot, and i live at the 3rd floor.
Thanks, and sorry for my english :P

i opened the mini, and i pressed down the antenna connector through the holes of the antenna plate, from the kitchen i get top speed, now, i moved the mini back to my room, i would say 8 meters from the router, and one room in the between.
I tried the speedtest and now i get the full speed, i moved the mini to the other side of the monitor, maybe there were interferences, or some signal shields, i don't really know.
So far it looks like it's working properly.
MAH.....that's DARK!

Airport very slow with Mac mini

I have a Powerbook and a Mac Mini. Both have airport wireless internet.
When I put them side-by-side, the Powerbook gets a strong internet connection, the Mac mini is very weak and often loses the internet altogether.
Both the Powerbook and Mini have 1 GB Ram.
Seems like they should get identical or at least very similar reception.
Help!

Yes, I would expect them to have roughly similar reception.
The Mac mini is certainly still under warranty. The Airport card inside your Mac mini is not considered to be a user-serviceable part. Therefore best solution - take your Mac mini to your Apple dealer, explain the problem, and get them to fix it.

Unibody Mac Mini Crashes

My Unibody Mac Mini Crashes when I switch my 1080P Samsung's input sources and when I switch back to the HDMI input source that the Unibody mac mini is on the Mini crashes and I have to hold down the power button to restart it.
I don't know why this is happening.

Sorry to hear you are experiencing this as well. Please see this post for more info:

Wretched airport reception on new Mac Mini

Me and this Mac Mini are not getting on at all.
I've set this machine up right next to my iMac G5. Both are accessing the same Airport Express wireless router that is in the family room down the hall about 15 feet.
The iMac G5 is downloading at 6x the speed of the Mac Mini. To download the same file from the same site the iMac G5 d/led at 125 KB/sec while the Mac Mini then got 24-25 KB/sec. Just to make sure, I then tried out my iBook, and it also d/l'd at 125 KB/sec (the file was cyberduck).
I tried to just transfer files from the iMac G5 to the mac mini using wireless, with similar results.
Have tried moving the machine all around the room, right now it is perched by itself on a dresser with no gain in performance.
I hope I have a bum unit, or one whose antenna has come loose. If not, there's going to be a real problem with the new Mac Mini.
Already I have had to use an ethernet cable to link the mini to the iMacG5 because the Mac Mini's airport reception is so bad that it can't stream music or video from iMac--four feet away.
Ouchy. Really looking for a report from another owner of the new mini so I can tell whether I have bum machine, or if these are the new titanium powerbooks.

Could you guys with the mini problems run the ping test? This will make it clear if you are having the same or a different problem as the iMac crowd. I suspect that the problem is the same.
Open Terminal and type
ping -c 30 <your router IP address>
you will get 30 pings on 1 second intervals something like this

Airport wont turn on mac mini

Hi all
this is an incredibly frustrating problem which i hope you can help with.
I have a Mac mini (intel) which was running happily running a fully updated leopard os, then for no aparent reason the airport would not turn on rendering wifi conections impossible. after hours of hunting for help and finding none i bought snow leopard and did a full install in the hope of retifying the problem.
unfortunalty the problem is still there, sometimes it says airport card not installed sometimes its there, but whatever it says nothing happens when i try to turn it on i press the turn on button but nothing happens.
for fear of the card itsself being faulty i bought a usb wifi dongle, istalled it as per the instructions yet still i cannot get wirelessly on the internet
can someone please help?
thanks

Try doing a complete reinstall again. Not an update, a fresh install.

Built-in ethernet port not working in unibody Mac Mini

Hi,
So ever since I acquired this new mac mini I haven't been able to get it to recognize any devices connected via ethernet. I obviously checked the cables and all is good there. I tried connecting it to another mac, and while the other machine was detecting a device (the mac mini) at the other end of the cable, the mac mini kept saying that the cable is unplugged or the device off.
After several days of having the issue I decided to remove the ethernet service from the network preference pane to set it up again but to my surprise, the built-in ethernet option was not available (I only got airport, firewire, bluetooth DUN, VPN, PPPoE and 6 to 4). At this point I tried removing the networkinterfaces.plist file form the system configuration folder in the system preferences folder to no avail. I then tried to zap the PRAM, NVRAM, reset the SMU, SMC and all that kind of things to get the port recognized by the system but no luck.
When I look at the system profile I get these weird results in Ethernet Cards:
pci14e4,4353:
Type: Other Network Controller
Bus: PCI
Vendor ID: 0x14e4
Device ID: 0x4353
Subsystem Vendor ID: 0x106b
Subsystem ID: 0x0093
Revision ID: 0x0001
Link Width: x1
BSD name: en0
Kext name: AppleAirPortBrcm43224.kext
Location: /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AppleAirPortBrcm 43224.kext
Version: 425.16.2
Comparing it to other macs I have It should read "ethernet" rather than that strange pci name on top and the kext name shouldn't read airport but something like AppleIntel and in location it shouldn't direct to the IO80211Family.kext package but rather to the IONetworkingFamily.kext.
So I popped in the system install DVD and fired up System profiler and at that point I didn't even get an "ethernet cards" option in the left side pane. So this is leading me to believe that the hardware is not being recognized at all, so maybe it's damaged. I did replace the HDD with a bigger one and change the RAM modules to bigger ones but I don't think I could have damaged the hardware in these processes, also I don't see how this would affect the ethernet port as it's integrated to Motherboard and didn't messed with it at all (I was very careful, to say the least!).
The last thing to do is reinstalling the system but I don't think it'll help (after seeing that the ethernet port is not even being detected by the install OS) but I need to offload all the data from my internal disk and at the moment I don't have an spare drive to do it.
So, what's the recommendation? A field trip to an Apple Store? Closest one is like 3,000 km from where I am right now, so...
Well, thanks for any pointers, suggestions and help in general.

I do not have any answers for you. Yes it appears to be reading what should be an ethernet card as an AirPort card. Have you played around with trying to install another version of Mac OS X other than the version that shipped with the Mac mini? Apple has long told us that we should not install a version of Mac OS X that was older than the shipping version. With the Mid 2010 Mac mini, the Restore DVD has the only version of Snow Leopard that will work with this Mac mini's specific hardware. At least until Apple releases 10.6.5. If you have installed other versions of Mac OS X, then erasing the HDD and installing the OS from the Restore DVD(s) that shipped with the mini may get you back to the point you need to be.
Unfortunately I think that you voided your Apple Warranty when you installed the different HDD. That was always a question in the past when folks wanted to open the former version of Mac minis and upgrade the RAM. But with the 2009 models folks started reporting here in the Apple Discussions that Apple was informing them that they had voided their warranty by opening their Mac mini. This new model made the RAM user upgradable, but the User Manual specifically states on page 43, 54 and 61 that there are no user serviceable parts in the Mid 2010 Mac mini except the memory.

Performance Issues with Mac Mini (Late 2014)

Dear All,
We have few Mac Minis with below mentioned configuration in our organization.
Mac Mini (Late 2014)
Processor : 1.4GHz dual-core Intel Core i5 (Turbo Boost up to 2.7GHz) with 3MB on-chip shared L3 cache
Storage : 500GB (5400-rpm) hard drive
Memory : 4GB of 1600MHz LPDDR3 memory
Graphics : Intel HD Graphics 5000
Mac OS Version : 10.10.2 Yosemite
We are using these Mac Minis for iOS application development using Xcode, but now we are facing lots of performance related issues. We are sharing issue related details with you & want to get some help to improve our system performance.
1) System is running very slow & take a lot of time to Boot.
2) Some time it never boots & we need to press start button several time.
3) When system goes in Sleep mode, then it takes much time to come to display screen to type Password.
4) Sometimes the whole screen moves Downwards.
5) Sometimes while during coding using Xcode in Simulator it shows some kind of Error “Unexpectedly quit”
6) Xcode runs very slow & it take lots of time in switching between files.
7) While closing any open application it take lots of time & show activity indicator for very long time.
8) Sometimes it doesn’t support iPad when we connect it using USB cable.
Our development team is facing lots of issues using these Mac Minis, so please can anyone suggest us that how can we improve our system performance & is this configuration is ideal to run Mac OSx 10.10 Yosemite Series and to use it for iOS application development.
Please try to help us to solve these issues & try to share some valuable comments on it.
Thanks

Dear woodmeister50,
Here i am sharing required screenshots which you have suggested to share.
1. Open up activity monitor and select CPU. Post the top 5 procersses
and their percentage of CPU usage.
2. Then select Memory. Post the values listed in the box at the bottom
or you can post a screen shot that area.
Please analyze these Activity monitor logs & let us know if you want to share some feedback on that. We will also try to boot & run our system in safe mode.
Thanks

General poor performance of my Mac mini

I have been using my mac mini for over a year, it continues to frustrate me how slow and unresponsive it can be even though I do very little with it, i.e organise photos and browse the web - usually looking for solutions to the poor performance problem!
I came a cross this app that has given me lots of information, unfortunately with my limited IT know-how there is nothing here that gives me any clues, as to the cause of the problem. I guess the red font is not good?
I'm sorry i can't be more specific about the problem other than to say that iPhoto and Safari the two programmes i use way more often than any other, keep giving me the beach ball. My internet speed is ok 25 Mbps down - 4.5 Mbps
Is there anything here that stands out as being wrong? if so any suggestions/ instructions for what I should do?
p.s. i had to quit Safari while writing this and have a report for this if it helps?
Any help much appreciated.
Problem description:
My mac is just generally very slow. I only use it to look at the internet and manage photos.

Hi Linc Davis
Thank you for taking the time to respond.
I got this information from a time when I was opening up iPhoto, and then going to the iCloud folder. To be honest it wasn't the most disastrous of events, I did get a few beachballs and when I opened up a shared folder the photos weren't loaded as normal. As I get more lengthy delays in carrying out any activities I will post back the console results.
Just as a bit more info, I don't consider my problem an update to Yosemite problem, if anything since updating performance has been improved from Mavericks.
Do you have any comments about upgrading RAM from the 4GB I have?
Should I act on any of the messages in red from the EtreCheck report?
Many Thanks
Duncan

AIRPORT EXRESS with airtunes - MAC MINI RECEPTION

HI MAC BOFFS,
I have just managed to configure a an airport express with airtunes, and managed to get it on the network, but music keeps dropping from the remote speakers. When i get sound it is excellent quality but only for a few seconds.
I have noticed that my reception bar on the top rights does fluctuate and at best is half (and has always) but for internet purposes it never bothered me.
The appartment is stud walls and i have put the router on ch 1 if this helps.:(
Is there anything i should do?
thank you.
i sot

1) The Mac Mini doesn't have great wireless reception. Try experimenting with the Mac mini in the same room to make sure that it is indeed the reception causing your headache. If it is, there are some Mac Mini wireless reception hacks on the 'net.
2) Are you in an apartment? It is possible that there are many wireless networks around from your neighbors and if they are unencrypted your Mac / AE may be hopping between different networks.

Poor WiFi performance on new Mac Mini ?

My new mac mini purchased a few days ago (late 2009) was exhibiting abysmal WiFi performance on 802.11n 5Ghz. I was barely getting 1Mbyte/sec through it, despite good signal strength (-50db), and my iMac which is feet away on -58db is giving almost 18Mbyte/sec...
Anyway - after much gnashing of teeth, and even placing the mini next to my extreme basestation I gave up, then tried, out of desperation, resetting the PRAM... Fixed!
Why on earth a brand new machine should need this doing, I'm not sure, but the old Alt-Cmd-P-R at boot up, waiting for the second BONG, and then letting it continue, fixed everything, and it now zooms along as fast as my other Macs.
Just for info - hope it helps someone!

These are pings from my iMac to .02 (mbpro) and .11 macmini
the mbpro is sat right next to the mac mini... rebooting the mini sorts this out... Come on, somebody must have this problem as well?

Airport connection timeout on Mac mini PCs works fine

Hi
I'm having trouble with my Macmini since I upgrade to Leopards latest updates. My girlfriends PC connects with no problem and also my company PC. It's just the Mac thats having trouble. I've had it for 2 years with Tiger and its just been working fine all the time. Then I bougth Leopard and a Time capsule for Christmas and I didn't realy had any trouble until the 10.5.6 update installed then it has been nothing but trouble. I did get it to work by following some instructions I found on the Net. For a day or two it worked fine then I upgraded the Time capsule then it was gone again. I bought the mac for it simplicyty but now its giving me a hard time. Anybody having a suggestion please

I have a similar problem. Though I couldn't get my Mac Mini (just got it 2 weeks ago) to ever connect through AirPort. My router (LinkSys) is in the same room as the mini. Sometimes mini can't even see my network but it does see a couple of other WLANs in my proximity.
I have no problems finding and connecting with my black MacBook and my girlfriends HP Pavilion.

Unibody Mac Mini 4.1 and leopard

We replaced a mac mini that had 10.5. Is there any way to get 10.5 on the new mac mini? We have a workflow client that will not run on SL due to Java 6 and something else I don't know about. I have installed java 5 and can get some functionality, but it crashes on an imposition editor/viewer. Am I destine to run a windows VM for the client, come on apple.
The software is Fujifilms, and they do not have a date for the release of the client that is compatible with SL.

There is no End User License Agreement to allow the use of the client version of Mac OS X in a virtual machine. So to even suggest to someone to do so is grounds to have your comment removed here in the Apple discussions.
Using 10.5 on a new mini is just asking for a lot of headaches. But I doubt that 10.5 can even boot a new mini.

Performance of a mac mini + Cinema Display

Hey all,
currently I use an Imac 2,0 GhZ, 2 Gig Ram , Core 1 Duo.
Actually I'm not doing much CPU intensive work, neither I plan to do so in the future. After going through some troubles with my current machine ( over the last three years, e.g. 2 x replacement of mother board ) I would like to try the mac mini.
Lately I was going into light video editing , imovie -- > i DVD --> burn --> end.
The longest thing was the DVD rendering / burning ... but this can be done, while I'm having a break, sleep whatever...
So guys and gals pls talk me into this setup and I will order by tonight
Any advice / experience made so far with similar user behaviour ?
TQ!

CPU wise the mini is quite a bit more powerful than your imac. The integrated Nvidia GPU in the mini
is quite good too. For what you are using it for the mini is going to be just fine. Just remember to get at least 2GB of RAM.

Poor Flash performance on G4 mac mini

Hi,
I've got a 1.25Ghz PPC G4 mini with 512mb running 10.4.11 that exhibits extremely poor Flash performance; jerky almost unwatchable video. I downgraded from Flash 10 to 9, and it only got slightly better, and most videos now require 10. I've heard the Flash drivers for Macs are awful; is this the problem?
Also, maybe possibly related, when I leave the computer on for awhile, the hard disk eventually, and magically, "fills up". After a restart, I have 1.55G of a 37.5G drive. When I leave it on for awhile, it'll get down to Zero KB, and become so slow that I have to restart it again, if it doesn't just crash outright? Is this a memory leak? Is the only way to cure it by wiping the HD and reinstalling the OS?

I think Boece has nailed it. Can you get more memory in your mini? I know it's a pain and the max quoted by Apple is only 1G, but I think a big part of your problem is just plain lack of memory. When the system does not have enough real memory to work with it will use virtual memory - use the hard drive as if it were memory. This really slows things down, especially when you have a hard drive that is way too full as yours is. You have very little ram to be running OS X and you've effectively blocked the system from the work around it wants to use to deal with this by having a hard drive so full. Add a resource hog like flash and the problem just gets worse. Every time I've added memory to a mac the page-outs have gone down and the system become more responsive. You have a lot of page outs. I've seen macs run all day and have zero - but that's with 4-6g ram. Still, the fewer the better. Here's a nice link to Apple's discussion of memory usage in OS X: http://support.apple.com/kb/HT1342?viewlocale=en_US
Also, flash will never run great on the graphics sub-system in that unit. I have a MDD G4 1.25 with a similar graphics unit and flash isn't great on that either. But for security reasons I would never run less than the latest version of flash - it is one of the main conduits of malware these days and although I've never heard of problems on the mac it's still not good to leave gaping security holes. Hope this helps.

Mac Mini won't boot after 10.6.6 / Airport update

I just reinstalled 10.6.3 on a unibody Mac Mini, updated to 10.6.6 - and it booted fine. I ran another software update, and it suggested two more updates - which I believe was an Airport Utility update and a Java update. Now the Mac Mini fails to boot, stopping at the Apple logo.
The last lines of verbose startup goes like this:
Airport: Link Down on en1. Reason 8 (Disassociated because station leaving).
Aut result for: (MAC address) succeded
AirPort: Link Up on en1
AirPort: RSN handshake complete on en1
AppleBCM5701Ethernet: 0 0 setFixedSpeed - logic error, speed any?
Suggestions?
H

I experienced a similar problem today after a recent upgrade to 10.6.6. I ran Tech Tool Pro 5 on the machine, which reported everything as just dandy after about 6 hours of testing, but it still wouldn't boot. Next, I tried booting in Verbose mode, which revealed that my iMac was hanging on:
AppleBCM5701Ethernet: 0 0 setFixedSpeed - logic error, speed any?
I used Safe Single User mode (turn on power, then immediately press and hold Shift-Command-S until text starts appearing) to boot to a command line. Single User mode provides instructions on how to mount the file system read/write. I executed the `fsck` command as instructed, and after a few minutes it reported that it had made changes to the file system. At that point, I skipped the `mount` command and went directly to `exit` to continue the boot process, which completed. I turned AirPort back on (I had it turned off), then rebooted normally without any trouble.
