IP Address Conflicts - iMac and Airport Express, Snow Leopard and Mountain Lion
In our home we have an iMac, two Mac notebooks, an iPad, an Apple TV and a Sony Playstation that all use wi-fi. I have a recurring problem. When several devices are connected to the Internet through Airport Extreme (wi-fi) downloads really slow down. Since the Airport Extreme is connected directly to a Motorola cable modem that also has wi-fi, I often shift my iMac wi-fi connection to the Motorola cable modem to speed up the Internet. Lately I have been getting an IP address conflict message in a pop-up box when I shift to the cable modem wi-fi. The system preference shows the IP address automatically assigned via DCHP. It also offers the option of DHCP plus manual.
I am now using Snow Leopard and intend to upgrade to Mountain Lion.
How can I resolve the conflict? Or, should I consider some other wifi network configuration? Is the upgrade to Mountain Lion likely to resolve the problem or make it worse? Can I use the DHCP plus manual to manually assign an IP address to the iMac to resolve the IP address conflict, and, if so, what it the procedure?
Is the DHCP assignment being done by your cable modem or your AirPort Extreme?
What is the exact text of the conlict message, and where does it pop up?
If your cable modem and your AirPort Extreme are both running DHCP servers for the same subnet (which they really should not be allowed to do), they must be set to assign addresses from disjoint pools.

Airport Express: Snow Leopard 10.6.3 / Vista Home Premium / connect problem
I have Snow Leopard 10.6.3 running on my Mac Pro, and I have an Airport Express for the little wireless network I am trying to set up....
...I can get my iPhone to connect - that was easy!
The problem:
My girlfriend is running Vista Home Premium on her HP laptop. She cannot connect to my network:
a) actually it comes up on her computer as being "connected to an unidentified network"
and
b) she continues to get "Internet Explorer cannot display the webpage" when she tries to connect to the internet.
Any ideas?
1) Is there a connection problem between Vista and Airport Express / Snow Leopard?
2) Anything special I need to do to let a Windows (or Vista specifically) computer connect?Possible risks after someone cracked the password and connects to your Wifi:
- Someone could sniff passwords when the password is transmitted in plain text (e.g. check for mails with POP)
- Someone could access shares that are not password protected
- Illegal use of your internet connection
But I don't know how likely that is. Your decision.
However, we now identified the Windows Vista Wifi settings as the source of the problem.
You can now play around with the different encryption settings in the AX and identify when Vista starts to not connect.
I now remember that I had to add the Wifi settings to Vista manually for WPA2 Personal (WPK) as the system messed it up when I connected with a click and provided the password. So if you want to try WPA2 delete the profile in Vista, probably restart and then add all the Wifi settings manually instead of clicking on an identified network. Vista is definitely able to use WPA2, so there should be no need to toggle between WPA2 and WEP once you configured Vista correctly. -
I am contemplating upgrading my OS from Snow Leopard to Mountain Lion. Currently, I don't have ICloud available on my computer. I also keep getting messages to upgrade my IPhoto to '11 version as well as Pages. I know, I'm behind, but my theory is if it isn't broke don't mess with it.
My concern is I don't want to lose my pictures and YES, I have backed up with Time Machine to an external hard drive. (I just hope that's good enough). IF I upgrade to start using ML OS, will I need to restore anything from my external hard drive or will I be able to start using computer as if nothing changed?
I know enough to be dangerous and I'm hesitant to upgrade for fear of losing everything. Would appreciate help. Thanks!Charmedgreen wrote:
So it's alright to "skip" downloading the Lion version first? I can go directly from Snow Leopard to Mountain Lion?
Correct, in fact, Lion is no longer directly available from the App Store.
Also, do I need to "empty my trash" before going forward?
No need.

I currently have Leopard, and there are no longer updates for it. So I must upgrade to either Snow Leopard or Mountain Lion. Without doing so I cannot update my itunes, and my ipod is no longer compatile with my mac. How can I buy the upgrade, since I do not have access to the mac store as that comes with Snow Leopard? I went to Best Buy and they said neither Snow Leopard or Mountain Lion can be bought there.
Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
Whilst Apple have withdrawn Snow Leopard from their stores, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $20 for a single user, or $30 for a family pack that covers up to 5 Macs. You can also purchase the code to use to download Lion from the same number (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:
http://www.apple.com/osx/specs/
If you are outside the US call your national Apple Helpline:
http://support.apple.com/kb/HE57
If you're in the UK, use this number: 0871 508 4400
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
To use iCloud you have to upgrade all the way to Mountain Lion:

I have updated my mac from snow leopard to mountain lion 3 days back. I had some important data in my library folder and it got overwritten. Is there any way i can get the data back from my snow leopard library folder?
I tried mackeeper to recover files but it could not. Any other way any one has tried to recover a system library folder after OS upgrade?No, it doesn't store a clone. You would have needed to make one with either SuperDuper or CarbonCopy Cloner.
If the files were in your ~/Library folder then they may still be there. As I said, you can access it by
going to your Finder "Go" menu hold the option key to choose "Library". I wouldn't think an upgrade would overwrite anything in ~/Library.
If you have a Time Machine backup you may also be able to use that to retrieve them. -
Hi I've just upgraded my MacBook Pro from Snow Leopard to Mountain Lion.

Can anyone please help me I really need these programs for my work. Thank you!
hi tuggerose
i think it is bad new for you. if it's any consilation i went through the same thing when i loaded mountain lion when it first came out. i think the problem is that mountain lion is a pure 64bit operating system and the software you have is 32bit. earlier os's were able to emulate 32bit but the new system does not. the answer is new software. i did it and it cost me a load of money and much angst so your not alone. -
I want to upgrade from snow leopard to mountain lion. So will I have to download lion and then mountain lion? Or can indirectly download mountain lion?
You can install Mountain Lion directly without going to Lion first. Just be sure your system meets Mountain Lion's requirements. There are a few systems that are Lion compatible but not Mountain Lion compatible:

I am on OS X 10.5.8 and I would like to get snow leopard or mountain lion, how do I go about upgrading to on of these?
You phone the Apple Store and order a Mac OS X 10.6 DVD, and if desired, update it to 10.6.8 and get Mountain Lion from the Mac App Store.

Hello, I have macbook pro, late 2008, OS X 10.5.8 and I want to upgrade to new soft, which one is the proper one for me Snow leopard or Mountain Lion, and what is the differences between those.
What do you recommend at this time for me.
Thanks a lotYou can upgrade to Mountain Lion, but you have to upgrade to Snow Leopard first. Buy Snow Leopard > http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
Then, make a backup, insert the DVD and upgrade. After upgrading, open Apple menu > Software Update and install the most recent version. Mac OS X 10.6.8 includes the App Store, so open it and purchase Mountain Lion. See if your programmes are compatible > http://www.roaringapps.com -

Run Software Update to download and install the latest updates for Snow Leopard.
You should now see the App Store icon, and you now need to set up your account:

Hi I just updated from Snow Leopard to Mountain Lion.
I write DVD's using Final Cut Pro, creating a DVD that plays HD and Standard Definition on one disk.
My problem is when I used load the disk on my G5 it would ask if you want High Definition or Standard Definition, now it just defaults to Standard Definition.(I'm using Apple's DVD Player)
Can I fix this problem?Addendum: I read on a post here (http://forums.macrumors.com/showthread.php?t=420169) about removing some kext files in order to trick OSX into thinking that there were no FireWire ports.
I followed the instructions and removed from /System/Library/Extensions/ the following files:
IOFireWireSerialBusProtocolTransport.kext
IOFireWireAVC.kext
IOFireWireFamily.kext
IOFireWireIP.kext
IOFireWireSBP2.kext
I restarted and BAM...Snow Leopard booted crazy fast and the mouse and keyboard worked instantly.
The System Profiler says "No FireWire ports were found."
So this tells me that the FW port is probably the culprit and is messing up the installation.
So how do I hack the Mountain Lion installer and tell it to ignore the FW port, which is obviously quite dead? Or is there something I can do to the Base system that is similar? -

Welcome to Apple Support Communities
Of course. Open the Mac App Store and purchase OS X Mountain Lion. Make a backup of your files with Time Machine and check that your applications are compatible > http://www.roaringapps.com
To upgrade to OS X Mountain Lion, you should have at least 4 GB of memory. You can check the amount of RAM you have in > About this Mac.
OS X Mavericks will be launched in weeks and will include new features > http://www.apple.com/osx/preview -
Upgrade from Snow Leopard to Mountain Lion: Airparrot stopped working
Hello,
I used airparrot on my appletv 3 and my <acbook (late 2008) to mirror my screen. However, I updated from Snow Leopard to Mountain Lion and now suddenly, Airparrot cannot find my Appletv anymore, it continues saying: "searching for devices...".
I already tried rebooting my macbook, disconnecting the electricity of the Appletv unit and removing the Airparrot app. All without result.
Can someone please help me as this is the only functionality I use my AppleTV for... I want to cry.... I can't even remember why I wanted to upgrade to Mountain Lion except curiosity!
Any insight is much appreciated.I don't use Air Parrot, so you should wait to talk to their tech support to see what they suggest before looking for an issue with OS X. I know nothing about using Airplay, but here's a bunch of help stuff:
About AirPlay and Airplay Mirroring
AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). For non-qualifying Macs you can try using Air Parrot.

Do I need to update Bootcamp 3.3 after upgrading from Snow Leopard to Mountain Lion?
Do I need to update Bootcamp 3.3 after upgrading directly from Snow Leopard to Mountain Lion? If so, what is the recommended version for my machine?
Other pros and cons we should consider? Not sure what is considered best practice.
We have a mid-2011 iMac (12,1) running Win7 64bit. Concerned about firmware updates not being compatible with Bootcamp 3.3. Firmware updates forThunderbolt port were part of post-Mountain Lion updater install. Not sure what other firmware/boot changes might have been applied to support the new recovery partition, for example. Will the 3.3 windows control panel still work safely?
Win7 still boots OK, at least for now. Backup is current.
I'd like to get the entire machine current again. Bootcamp 5.0 didn't want to download (appeared to hang writing to my external drive, which is otherwise fine). Bootcamp 4.1 refused to install on Win7 (claimed it wasn't for my machine, so I aborted. Downloaded from apple support page directly).
I've searched the forums for this specific question - I see plenty of info for upgrading Bootcamp 4 to 5, but nothing for 3 to 5.
Thanks much in advance,
-bAppreciate the quick response.
There are basically 2 schools of thought here:
- If it ain't broke, don't fix it.
- Don't fall off the upgrade cycle (apply patches whether you have an issue or not in order to ward off trouble before it happens).
I don't have a specific issue that I'm chasing on the Win7 side right now. I'm attempting to address having fallen off the upgrade cycle by staying on Snow Leopard too long.
I appreciate that the Win7 side under bootcamp is its own thing (upgrades to Mac OS don't cross over or effect the bootcamp partition) - except where firmware upgrades coming out of Mountain Lion change the hardware interface to Win7. Hence my questions.
