Mac Mini & ethernet issues

Hello, i bought a mac mini just a couple of weeks ago and upgraded it to OS 10,7,4.
it was all running just fine for a start so i made an account for itunes and turned off the computer. But now, the mac mini just does not connect to the internet even when i plug the ethernet cable. I thought it would be a wireless issue but i realized that it happened even by cable.
I'm a little bit confused about this because the network utility says there is no problem (i can ping and traceroute) but safari doesn't open the page.
As a matter a fact, the only browser that works is Chrome, which only opens this forum's page and gmail...
Please help

No it didn't take me to apple's homepage. However, i can ping and traceroute to it without any problem.
I have read discussions about similar problems (on wifi) and tried to boot as safe mode.
Gratefully, it works, i can open every single page... but i still don't understand why does this happen on safe mode and not on the regular mode (i'm not going to log as safe mode every time).
Any idea?
Thanks in advance

Mac Mini ethernet read / write speeds different

Hello.
I have a 2.3 GHz Intel Core i5 Mac Mini running OS X Version 10.8.4.
I recently bought a Synology ds212j NAS, and started to transfer some files across my home LAN.
Everything was running fine until I noticed that the transfer had started to go really slowly.
At first I thought it was the NAS, but after exhaustive testing I think the problem is with the Mac Mini ethernet port.
I ran the LAN Speed Test program against the NAS and got the following results (with the NAS plugged directly into the Mac Mini):
Writing (Upload): 54 Mbps
Reading (Download): 689 Mbps
I get similar results when running against my time capsule:
Writing (Upload): 44 Mbps
Reading (Download): 767 Mbps
Can anyone explain what might be going on? Is it a defective ethernet port? Are there any steps I can take to further diagnose / resolve the issue?
Thanks,
Scott

Thanks for replying Johnathan.
I understand that write / read speeds can be different on a hard disk, but the key thing here is that the speeds changed suddenly - I was getting similar write / read speeds and then something changed (I don't have speed statistics for that).
One other thing to note is that if I plug in an external drive via USB I get write / read speeds the same.
This all makes me think that something has changed with the Ethernet port. Either it is malfunctioning or there is a cache issue etc. The problem is that I don't know how to do further diagnosis, or how to resolve.

I have an 6 year old mac mini having issues. I can turn it on, get the apple logo and blue screen and nothing else.....help!!

i have an 6 year old mac mini with issues that started two weeks ago. I can turn it on , get blue screen and turning circle and nothing else......help !

Hi,
Have you tried some of these? http://support.apple.com/kb/ht1533
The first things I would try would be to press shift during start up, this will boot into safe mode.
I think you'll need to purchase a copy of Snow Leopard to re-install the OS.
There's another couple of suggestions here; http://support.apple.com/kb/TS1417 where you can boot into single user mode and look at repairing disk permissions if that's the problem.
I would hope that if you could boot into safe mode or single user mode, then that may automatically rectify your current issue. If not, then I'm pretty certain that a fresh install will be the ultimate answer.

Mac mini having issues with system preferences retaining settings

Mac mini having issues with system preferences retaining settings; this was present with Mavericks and now Yosemite after installation. Did try removing com.apple.systemprefs.plist file (library/preferences folder) to trash, but couldn't find it in trash in order to empty it. Upon reboot the file is still missing. Please don't suggest reloading Yosemite, have very slow internet connection, Yosemite took 7-8 hours to D/L.
Any troubleshooting suggestions out there? thanks

Well, I'd open Font Book, it's included with OSX, & see what it says for Validate & Duplicates.
I would also like to add I am new to Apple computers and I'm doing my best to stay up to par with whats what and understanding!
No problem, we were all new to everything once, do let us know if you need more help or clatification.

Mac Mini Ethernet SSL connection issues

Hi,
Up until recently I have been using my Late 2012 Mac mini with a WiFi connection. Recently though I've had reason to switch to a Gigabit Ethernet connection (short version, moved from UK to Canada, living with in-laws and they have a crappy wireless router that can't hold a stable connection for more than a few hours).
However, I'm getting a really odd Ethernet network issue where my mac will "corrupt" SSL connections. This normally manifests itself in web pages not fully downloading, images becoming corrupted, or errors when downloading files. The last one is particularly hurting as I have been doing some heavy downloading of DMG files and other installers, all of which are a 100% guaranteed fail with DMG files reporting as being corrupted if I try to open them.
I have also lost my time machine backup as OSX has reported that this has failed verification and needs to be created new; I accepted creating a new one (reluctantly) and the backup now fails to complete every time it runs - either the wireless cuts out or the SSL connection corrupts the backup.
I have a 16-port GigE Switch (Netgear GS116) with a number of computers and the home modem plugged into this.
I've tried the following to look at this:
I've tried (and tested) a number of different Cat5e and Cat6 cables. These all work fine with other Windows / Linux machines and according to my cable tester all check out. 100% of the cables I own produce the error leading me to believe that it's not a cable problem.
Problem occurs even if the switch is bypassed and the mac plugged directly into the modem.
Problem does not occur (for web pages and small downloads) when plugged into wireless - this is just sloooow and as the router seems to develop issues with DNS over WiFi, I have to reset it every few hours so long term downloads fail.
I found an article (which I have now lost the URL for) where someone suffered intermittent network issues with Ethernet that they resolved by un-checking the "Enable automatic connection" on the 802.1X page of the network settings. This appeared to help for a couple of days and I enjoyed fast Ethernet and downloads once more. However, today the problem is back in force.
I am able to download files from a windows machine (well, except for downloads via the App store) and then transfer them over the network to the mini with no problems at all - the corruption issue only seems to occur when SSL is involved.
So I'm wondering what it could be and how I would go about diagnosing the issue. I'm more familiar with Windows / Linux systems, having not owned a Mac since the days of System 7 - the mini was bought so I could play with learning XCode and try my hand at Mac software development.
Thanks in advance,
~MrBasset.

Mac Mini Freezing Issues

So, I recently bought a refurbished Mac Mini, late 2009 model. It worked fine for the first few months, but after moving back to school, it started acting oddly. First, it had problems booting. It would freeze up during the boot up, or occasionally right after if finished booting. After messing around with it, it started working fairly reliably again. However, every once in a while, under moderate use, it would freeze up and would have problems restarting. I came to the realization that it was probably overheating, and tried a few tricks to get more air to it. This worked…
For a while. Last week, it died. It would get to the gray screen with the spinning wheel, and then freeze. It couldn't get past this step. In desperation, I took it into the Apple store, as it was still under warranty. After several days, they fixed it, but in the process, had to replace the hard drive. Luckily, I had a back up. Reset the computer, reloaded the back up, and started to use it… only to have it freeze again.
I noticed that every time it crashed, it seemed abnormally hot. I think this may be an overheating issue, and I have taken steps to monitor it (I currently have a temperature monitor watching over the CPU temperature). I just wanted to know what other people thought.
My current set up is thus:
Late 2009 Model Mac Mini, 2.53 GHz Intel Core 2 Duo
Dual monitors, connected via adapters to the Mini-display port and mini-DVI port
Ethernet internet (limited wireless here in the dorms)
Apple keyboard and Logitech mouse
Verbatim external hard drive, 320 GB, connected via Firewire 400/800 cable
My current thoughts are that it's either due to the dual monitors stressing out the video card, or the external hard drive. I've noticed that the external hard drive is constantly on when it's plugged in to the computer (it gets it's power via the firewire cable), and that if I leave the external drive plugged in overnight, the computer can occasionally act sluggishly.
If anyone has any further insight into this or can verify my hypothesis, that would be great. Thank you for your time.

After looking around online some more, found that there are many complaints with this specific hard drive. The main issue, it seems, is that it has limited ventilation, and therefore has issues staying cool. Unfortunately, due to the length of my firewire cord, the external hard drive typically has to sit fairly close to the Mini, usually resting on top of it. So, if this is right, then it's the poorly designed external HD overheating, which in turn overheats the Mini to the point of failure. I'll look into getting a better external to replace this one, and for the time being I'll only have it connected for brief periods for backup.

Mac Mini - Wifi Issue - Not Finding Established Network

Purchased and tried to setup a late 2012 Mac Mini (2.3 Quad-Core).
Current Wifi Setup
- Cable Modem into Airport Extreme.
- Airport Extreme (Base) is pushing to (2) Airport Expresses.
- (1) of the (2) Airport Expresses is underneath the desk where the Mac Mini is located.
- The devices currently on the network include: (1) MacBook, (1) Apple TV, (2) iPads and (2) iPhones. Everything is connected to the network and running properly.
Issue
One of the first things I attempted to do when I started up the computer, was join my home network. I searched for the network, found it and entered in the password. The Mac mini would not accept my password (the password is correct), claiming either password was incorrect or the connection timed out. I went to the Airport Utility and noticed the Mac mini was not locating/finding the Airport Extreme (Base), but was attempting to connect to the Airport Express underneath the desk. An important note the Mac Mini and the Airport Extreme are approximately 20 feet apart.
Here are some the methods I used to attempt a fix:
I turned off the Mac Mini Wifi and reset all (3) routers.
I updated the firmware of all (3) routers, reset them again.
I updated the OSX to 10.8.2
I ended up loading the Airport Utility on my Ipad and taking it back to where the Mac mini was located. From the attached picture, you can see on the bottom the Ipad correctly showing the Network and the on top show Mac Mini still searching for the Network.
I ended up hooking the Mac mini though Ethernet using the Airport Express underneath the desk, which is a fix however that an issue if the wifi is not working.
I’m currently at work and will have a chance to work on the computer this evening, does anyone have a suggestion on how to fix this issue?
Thank you in advance.

Mac mini ethernet speeds cut in half by snow leopard?

I upgraded an old mac mini (2,1) of mine from Leopard to Snow leopard this weekend. Same physical hardware and setup results in a dslreports.com speed test of the ethernet at about 50% of that of the leopard speeds (about 11.5Mbps over ether). I have another slightly newer C2D mini on SL that is doing 10Mbps on the same network. When I change startup disks to the SL disk, I end up with a max of about 4.5-5.5Mbps. Any ideas? I ran "Tune for High speed" on MLCC to open up the MTU size and such on both machines. Same results. I didn't try to update the existing partition (working Leopard) to SL, I scratch installed it on a new partiition.
Any ideas on what I should tweak to get the SL side to get to the same performance? I can always upgrade (painfully) the Leopard side and test it and then revert if it has the same poor results)...
Thanks,
Jim

Sorry, I checked all the obvious. The ifconfig shows both ETH0 running with the same parameters.
Wifi is off on both partitions.
Sadly no obvious issue as to the 50% loss of throughput.
Any other ideas out there? I also made sure IPv6 was off where possible. Again another Mac Mini on SL is also on the same ETH network doing 13Mb+ to the dslreports.com/stest sites...(the good partition is the same, bad is doing about 5-6Mb/s).

Mac Mini Connection Issues

Hello all,
Just got Verizon FiOS and I'm trying to get my server back up an running. When I had Optimum, the server automatically recognized everything and i was up an running very easily.
Now, with the new ISP and router, it can't connect to the DYNS... when i look at the regular network preferences it says I'm connected fine through Ethernet, but still no webpages will load.
Is this a firewall issue? Is the dynamic name server necessary just to go online?
This is really frustrating, and I would appreciate any help, thanks!

Hi,
I have FiOS (with the ActionTec router) and just recently stumbled down this very path. Here's what I presently have running:
My Mac Mini is using the manual Ethernet configuration: fixed IP, router IP set to the ActionTec's IP, DNS servers set (in order) to 127.0.0.1, the ActionTec's IP, and finally the DNS upstream from the ActionTec.
I went into the ActionTec and set a DNS entry for the Mini's IP. This probably doesn't do much in the end but it doesn't seem to cause any smoke to come out of any boxes, either.
You definitely need DNS - I had to read and re-read the "Setting Up DNS for Your Server" section in Getting Started just to get where I am (and I'm still not sure I'm in the right place!). It seems to be important for the OS X services to be able to resolve names they care about, hence the 127.0.0.1 business. (This is pure theory on my part...)
After going through the whole Getting Started process and ultimately wrecking Open Directory after trying to get iCal going I sure wish I had printed out the Installation and Setup Worksheet before I started. It might have saved me the Biblical grief I'm about to endure trying to get Open Directory resurrected.
Hope this helps,
Dave

RealVNC with Quad Core Mac Mini "Refresh Issues"

Upgraded my Mac Mini server from a dual core to Quad Core machine. Headless machine, hence used RealVNC to administrator it. So when I utilised RealVNC, connecting via an ipad and the quad core machine had "Refresh Issues"!! Went back to the Dual Core machine and you can view everything in real-time! Can't explain it and the RealVNC people can't understand it either, yet!!!???

It has a wired ethernet connection, the wireless is on but more for "location" services. And no USB 2.0 or 3.0 devices attached, in fact it's headless, and only the power and ethernet connection attached. But interesting to learn of the wireless issues on the new mini's. Thanks!

Mac Mini Bluetooth Issues

Hi there, I've recently took purchase of a new Mac Mini (my first Mac) and am loving it, apart from the problems I'm having with the Bluetooth functionality.
I've been trying to pair my new Apple wifi keyboard and have not been succesful, I can't get the mini to recognise that there is a keyboard (I've also tried pairing 2 different mobile phones, and anther laptop with no success).
I've tried a what was suggested in another thread (powering mac and key off for a few minutes, with power cable/batteries removed) but this hasn't worked for me.
I'm not at a total loss, as you can see by my typing of this Topic , however it would be cool to get the BlueTooth working on this Mini.
Any help or suggestions would be greatfully received
Dan

I am having similar issues. The bluetooth range with the apple wireless mouse and kbd is VERY short. If the mouse is more than a foot or so away, motion becomes clunky. I also tried this with another bluetooth mouse (different brand) and had the same problem. I've gone though making the mouse and kbd favorites, but about half of the reboots, the mouse isn't found (when it's less than 3 feet away).
The computer is completely up to date. I've installed every OS firmware, keyboard update etc available.
Incidentally, I've tried both mouse and keyboard with other computers, and they work perfectly at longer ranges (10ft or so).
I bought this system to be my media center, but if this persists, or I can't find a solution, I'm thinking about bringing it back.

Mac mini wifi issues

Had my Ipad mini for about a week. At first, the internet connection over my Airport/time capsule( which I bought a couple months ago, so it should be the newest generation) appeared to be fine although, I noticed that the signal bar was always a single to double bar (if that's how it is called). Now, from time to time it even fails to connect.
I am now in my living room in front of my mac mini set, which is itself connected to the internet over Airport/time capsule. The Airport is about 20 meters (abt 65 ft) away. The Wifi signal of my mac mini shows full capacity. My Ipad mini signal bar...it just says" iPad". While (when) connected I also have issues with iPad's ITune Wi-Fi sync. Connected by cable, checked the sync over wifi, removed the cable and Ipad disappeared from the Itune screen. I reset the Ipad, connected and did the whole procedure with Itunes and the iPad icon sticked to the itunes screen for a while but after about an hour disappeared again.
Now the ipad won't even connect.
When this thing works, it is a wonderful item. When it doesn't, it is a source of frustration. Can anyone help to solve this connection problem (resetting won't work) ?
thank you.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Mac Mini Ethernet port gone bad, doesn't show in network preferance pane?

My friend 's Mac Mini was doing fine then he shutdown disconnected everything and brought it over to my house for LAN games. He then couldn't get online through my router. I told him go to his network pane to see what kind of error it was giving, cable errors IP but no internet...etc, and only internal modem was displayed in the list. So I immediately went to his port setting and ethernet was checkmarked. So then I thought well maybe some PMU reset problem so I tried the resets and still not present from the network pane. So then I hooked my external hd to his firewire as a startup drive to eliminate that it just wasn't a software problem and it is still not showing up on network pane. I then skimmed through some online articles and things but to no avail. I just was thinking it was a 5 minute drive from his house to here and he said didn't do anything different from the other times he was here but something must have jarred it or perhaps just a coinseidense that the ethernet port went out when he was coming over. And to top it off he had made arrange for next weekend to sell it to a friend and get a new Intel iMac, which right now has to be put on the backburner until he has a working unit again. Applecare is up so that is out of the question. Any suggestion out there would be appreciated. Or is it just beyond easy fixes and has to either be repaired or keep and save from scratch for a new one?

OMG, guys I feel so dumb the new update to Tiger changed the way network pane worked so that was the whole problem its normal under 10.4.5 so plugged in a good cable and it came up fine go figure right. For being Apple certified for repair I sure looked past such an easy solution.

Mac Mini startup issue

So, earlier tonight, my computer was acting a little strange (it seems to have been flaky after updating to 10.4.8 lately) and after restarting, I get the gray apple screen, and the spinning indicator, but nothing else happens, other than more spinning. I've tried to boot from CD, or in safe mode, or open firmware, even, but nothing happens. I have a feeling that this is because I'm not using an Apple keyboard, but a logitech one. So I guess I really kind of have two questions, namely-what can I do to force a boot from a CD in this case, and, afterwards, what do you suggest I do to fix my computer? Do I need to reinstall the OS, or just repair disk permissions? Any help on this would be appreciated.

I have the same exact issue! I have also tried everything. I have a Intel 1.66 GHz core duo Mac Mini (refurbished) using a Mac Keyboard and still nothing happens.
My wife told me that it went into some kind of programing code and she thought it was a virus... ACK! and rebooted it. This is when the problem began.
I have tried using the keys to safe boot and boot from the OS X disk to no avail. The only thing that works is holding the option key down and it show the MacHD icon. I can't get past that. I have tried to use my external hard drive to boot to, but it doesn't recognize it.
I recently used software update to install the latest patches from Apple. It was running fine for a few days until this happened.
