Back to my Mac not working between Snow Leopard work iMac and Lion home iMac

I have a 3.06 GHz Intel Core 2 Duo iMac at work running OS X 10.6.8.
I have a 2.7 GHz Intel Core i5 iMac at home running OS X 10.7.2.
At present, I am unable to upgrade the work iMac to Lion because I need to run Intel's FORTRAN compiler, which does not yet work under Lion.
I have upgraded my MobileMe account to use iCloud on my home machine. Because my work machine is still using Snow Leopard, I can't use iCloud on that machine just yet.
Initially, even after upgrading to iCloud on my home machine, I was able to use Screen Sharing from either computer to use the other computer. I accidentally clicked "Turn Off Back to My Mac" in the MobileMe settings of my work machine. When I click "Turn on Back to My Mac" to try and turn it back on, I consistently get the dialog box "Unable to start Back to My Mac Back to My Mac could not start because of a MobileMe server error. Try again later. If this problem persists, contact MobileMe Support." And hitting OK brings it back to the off state. So I can not turn on Back to My Mac at work, therefore I can not connect to my work machine from home to use Screen Sharing like I want to.
Has anyone else encountered this problem? Has anyone found out how to turn Back to My Mac back on in such a case?
Thanks for any help you can give,
Adam

Hi,
the current version I had was 3.2(5612) but having just checked no a newer 3.2.1 has just been released. Let me do the upgrade and see how I get on.

I just update my Mac operating system from Snow Leopard to Yosemite and now have to upgrade my Epson Printer WF3540 so that it will be able to scan. Will Adobe be compatible with these softwares?

Hi spiritentrep,
What Adobe software are you referring to? Are you using Acrobat? You should have no problems running Acrobat XI on Yosemite, and as along as you have compatible scanner drivers for your Epson, you should be fine there as well.
Best,

Back to My Mac not working-a diagnosis and a solution

Hello all,
I own a small business and relied on Back to My Mac while traveling. I have had connection issues with BTMM since MobileMe was discontinued. I have found a solution but it is not an Apple solution. Skip to the end if you'd like the straight dope.
FYI: I have exhausted all possible Apple-centric solutions, to the best of my knowledge. This was verified over the phone during an extensive troubleshooting session with a senior Apple specialist. All Macs and OS involved are optimized (in theory) to work with Back to My Mac. The appropriate file sharing options were checked. Users had appropriate access privileges. I have a valid MobileMe ID that has transferred over smoothly to iCloud. Firewall settings were not the issue.
But before we go further, if you are having BTMM connectivity issues, you might want to examine this thread:
https://discussions.apple.com/thread/4071540
And see if it does the trick for you. It seems to have worked for a lot of people. But if it doesn't, please read on.
I have an iMac at my office that I connect to. I have a MacBook that I use to make the remote connections. Before MobileMe was discontinued, I read all support docs on how to make the transition to iCloud. Nevertheless, once MobileMe was discontinued, I began to have BTMM connection issues. My Macbook could "see" my iMac, and vice versa, but once connection was attempted, either through "Share Screen" or "Connect As…", the status bar would run indefinitely and no connection would complete.
First, I tried the Keychain solution indicated above. No dice.
Then I saw the System Preferences>iCloud message that Back to My Mac required NAT Port Mapping and/or Universal Plug and Play settings on my router. I have an old Linksys router, and I was able to upgrade its settings to UP&P, but not to NAT Port Mapping. The situation did not improve.
I went to an Apple Store, spoke with a pair of salespeople who informed me that the problem would most likely be solved by replacing my old router with Airport Extreme, which would automatically upgrade my network to the necessary UP&P and NAT-PM protocols, and if any issues existed after that, they would probably be firewall-related, which I could either fix on my own or talk to an Apple person about.
After installing Airport Extreme, the situation did not improve, and I called Apple Support. I entered the serial number into the web page, and was informed that I was not qualified for tech support because my warranty had expired, even though I had made the purchase the previous evening. I checked the option that indicated that I thought this was in error and that I was in fact qualified, and ten minutes later, I received a phone call from Apple.
At first, I was on the line with a Airport Extreme specialist, who ran down the Airport Utility checklist. With my wife at the Macbook at home, and myself in my office at the iMac and on the phone with the Apple specialist, the troubleshooting began. Once it was apparent that nothing was working, I was transferred to a "senior" specialist who indeed knew everything under the sun about networking and Back to My Mac, at least as far as I could tell. We checked various settings on all devices, Airport configurations, iCloud account validity, my network's firewall settings, etc.
Finally, the specialist suggested we check the settings on my home router, which was supplied by my ISP and not an Apple device. I asked him why. He said that if we enabled UP&P and NAT-PM on my home router, that would probably help make the connection. I informed him that while that might be a short-term fix, I travel as part of my job and need to make remote connections to my office, often from places where I have no control over the router settings. He informed me that because of those "variables" I might very well continue to experience connection issues, and that in some locations I would be able to connect, and some, not.
On the heels of all the time and money spent thus far, I was in disbelief. We spent some more time affirming beyond question that he was actually telling me what I thought he was telling me, and I cordially thanked him for his time and we ended the phone support session.
THE STRAIGHT DOPE: I learned from a senior Apple specialist that network and router settings not only have to be just right at the server location but *also* the remote location in order for Back to My Mac to work. Simply having an iCloud ID is not always enough. If you travel, you most likely have no control over router settings at your hotel, coffee shop, etc., and if you rely on remote connections as part of your job, you can't afford to take the chance that wherever you reside might not be BTMM compatible. I signed up for LogMeIn Pro, at a cost of $59.95 a year. It has screen sharing, file sharing *and* iPhone access, which BTMM does not offer. My remote connections are now almost instantaneous and without issue. Problem solved.
Please note, I have no ax to grind with Apple, I enjoy using their products and believe they are superior to Windows machines. I am also more than happy with the level of expertise, courtesy and efficiency of their support people. The Airport Extreme that I purchased is pretty cool, has kickass wireless signal, and has reduced the amount of wiring on my desk thanks to its wireless printing and hard drive capabilities. I feel a little burned that I bought it for no reason, but I have 14 days to return it, no questions asked. We'll see.
In conclusion, Back to My Mac does not seem to work as advertised. I am curious if anyone has had a similar experience. Hope this helps someone or at least, saves you some time.

Thanks for your thorough post. I too need to use BTMM on almost a daily basis for my job, and it has fallen short countlness times. I too have taken great pains to check all of the typical trouble shooting steps within iCloud and in the Apple keychain on each Mac etc, but after the latest rounds of system updates from Apple a few weeks ago to Mountain Lion, BTMM on one of my Macs is completely broken and unusable. I would concur that if you need remote access for "real" mission critical use, just bite the bullet and pay for a service like LogMeIn. You won't regret it and you will get real software support.

Can I up grade my existing software on my I mac 9,1 to snow leopard & then to mountain lion software ?

Can I up grade my existing software on my I mac 9,1 to snow leopard & then to mountain lion software ?

Yes, you can do that according to specs yours is early 2009.
http://www.apple.com/osx/specs/
Note that 2 GB RAM is suggested as a minimum but 4 GB is more realistic for good performance.
EDIT: Also, check for compatibility with any third party apps.

What's the difference between snow leopard 10.6 and 10.6.8?

Hi, I was just wondering if i buy snow leopard 10.6 will i be able to run iTunes 7? I'm currently on 10.5.8 and so i cant connect my iPhone 5 to iTunes. Are 10.6 and 10.6.8 different things or are they the same?
Thankyou!!

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 withdrew 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.
UPDATE:
OS 10.6 Snow Leopard is once again available from the Apple Store:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and in the UK:
http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
but nobody knows for how long it will be available.
To use iCloud you have to upgrade all the way to Mountain Lion:

Time Capsule Back to my Mac not working

Hello,
For the last two weeks I am not able to connect to my Time Capsule at work, before I saw it automatically on my iMac/MacBook Pro at home.
I already removed and rentered my credentails on the time machine for Back to My mac, unfortonatelly this didn't fix it.
What can I do?
Thanks in advance.
Greetings,
Robin Riegman

I have a similar problem. I had a new hard disk installed and upgraded to Lion at the same time. The IT person who did the job set up iCloud as a backup. Now when I connect my external drive, Finder doesn't see/recognize it, so I can't continue to do (or use) Time Machine backups. I do not want to back up my data to iCloud, but Apple's main object with Lion and Mountain Lion seems to be to force users to use iCloud. It doesn't give you a choice; you can't go back. When I try to sync my iPad to my Mac or take my data off iCloud and back up my Mac with Time Machine (external drive), the program menacingly threatens to remove all the data that I want to back up from my computer, leaving me with no data in iCloud or my Mac.
@r.riegman: sorry I can't help you. I'm going to try the Genius Bar, although Apple warns that backup issues are not supported.
In essence my question is: how can I go back to external drive backups with time machine without losing all my data after an initial designation of iCloud as the backup?
Will someone please r.riegman and me? The more time goes by, the more unbacked-up data we accumulate.
Thank you!

File Sharing between Snow Leopard MacBook Pro and Mac OS 8.6 Powerbook 1400

well ok, for some this might sound ridicule. Why should I still be using a 13 year old PowerBook. Let me tell you, this is writing/typing heaven, Zen-like; no distractions at all, no twitter, no internet (although possible), no emails just pure you and your text and if you spin down the HDD, absolute silence. as said before pure Zen writing heaven. and on top of that you're typing on the best keyboard ever on a laptop.
As you might see I love my vintage masterpiece of a laptop and use it on a regular basis. Just one Problem.
Since I Installed Snow Leopard on my MacBook Pro 17" I just haven't been able to establish a connection between the two machines.
I have to admit, I'm not that versed with OS 8.6 but with 10.5 I had absolutely no problems accessing the shared folders on my MacBook Pro and vice versa.
My first thought was to activate Appletalk on the ethernet on my Macbook, which I failed to find anywhere. The Apple Discussions Forums revealed that Appletalk has been dropped with the introduction of Snow Leopard but all the entries where regarding printing issues with shared printers, I didn't find anything about actual file sharing and thus did not get any clues how to share files between my two machines.
My PowerBook 1400cs/166 runs on 8.6 and I use a Global Village Platinum PCMCIA card (modem and Ethernet combi card). this setup worked perfectly with 10.5 but I have not been able to make establish a connection since running 10.6 on my MBP.
I am really desperate since I heavily depend on being able to exchange files between those two machines through an ethernet connection.
So I kindly ask anyone who might be able to help me to please consider posting any solutions or at least ideas which could help me with my problem. I really would greatly appreciate any effort whatsoever.
Thank you very much for your time.
EDIT:
What I forgot to mention: strangely enough, when I enable Internet Sharing on my MacBook Pro (through Airport) to Ethernet, my PowerBook 1400 can connect to the internet without any problems.

First of all let me thank you very much. It actually works (partially).
There seems to be a problem though. While I can connect perfectly from my MBP 10.6 to my PowerBook 1400, the other way round doesn't work.
My MBP does not show up in the Network browser of OS 8.6 but I could life with that.
The problem is that if I try to connect to my MBP from my PB1400 by entering the IP directly a alert message appears reading that the "User Authentication Method required by this server can't be found, please check the AppleShare folder in the Extensions folder and try again".
Do you have any clues what I'm doing wrong or where the problem may lie?
PS.
Even if you may not be able to further help me with this problem, I ow you a great deal of gratitude and am very thankful for your help so far. At least I can exchange files between the two machines and that's what I needed in the first place.

New Macs not shipping with Snow Leopard?

I just bought 2 Mac Minis for media playback use; I ordered them on 9/9 and figured they'd come with Snow Leopard (the Apple Store has a "ships with Snow Leopard" banner at the upper right, even).
However, they both shipped with 10.5.6 installed, and a DVD in the box also with 10.5.6 - no sign of Snow Leopard.
Any ideas on what's the best way to get this remedied? Visit a store, or phone support? I just spent 10 minutes clicking around support.apple.com but it kept sending me in circles.

Ha
I called support -- they did help me out, but it went like this
Me: Hi, I just ordered 2 Mac Minis, they said they'd come with Snow Leopard but when they arrived they had only Leopard
Support: do you have the Mac on right now?
Me: No, not now, but I do have serial numbers and order number
Support: Oh. Because a couple people have complained about that, and I was able to help them click on the Apple menu and say About This Mac and see that the version number was 10.6.
Me: Er, no, I'm not that [must... resist... urge... to... say... "clueless"...] ... hasty. I'm quite positive that the preinstalled version, and the only DVD in the box, was 10.5.6.
Support: Oh. I'm sorry. Well, have you heard about our up-to-date program? [http://www.apple.com/macosx/uptodate>
Me: Yes, but I'm not interested in paying $20 for stuff that was supposed to come with what I already ordered.
Support: It's not $20, it's $9.95.
Me: Right. And I need two of them. Sorry I was off by 10 cents, but I'm not interested in paying anything at all for this, actually.
Support: OK, let me look into this.
... long pause
Support: OK, and you've checked the entire box, and the version number, and it's not 10.6.
Me: Yup, quite carefully, a number of times now.
and then some more pauses, confirmations that I did check the installed versions, and apologies for the slip up, and they're sending me the upgrade.
So, in general, helpful, though this whole thing has been an extra set of hassles I wasn't expecting... Fight Club had it right, "the things you own end up owning you".

How can I sync "On My Mac" iCal calendars on Snow Leopard with iPhone and Google Calendar?

Hi,
(I've done a lot of searching for a clear answer but without success.)
Can someone please advise how I can get the "On My Mac" calendars on iCal v4.0.4 (running under Snow Leopard 10.6.8) to sync with an iPhone and Google Calendars, 'over the air' (i.e. not via iTunes) and both ways (two-way syncing).
There was a great bit of software called Spanning Sync which did it all but it's now discontinued. I'm running Snow Leopard and do NOT want to upgrade to OS Lion.
I've tried the iCloud route but it just creates an extra set of "@me.com" calendars under the "On My Mac" calendars - it is not syncing the "On My Mac" calendars themselves (and I want to use the "On My MAc" calendars as the master dataset (the 'Truth database' to use an Apple term!).
... And the same happens when I try to sync my Google Calendars: another set of "@google.com" calendars appear.
Now instead of 2 calendars in iCal I have 6: 2 On My Mac calendars, 2 iCloud ones, and 2 Google ones. (This is not progress Apple!)
Hope someone can advise.
Many thanks.

Thanks Winston. I'm aware that the 'on my mac' calendar doesn't get picked up by iCloud. I'm wondering whether anyone can help with the best alternative solution for synchronisation of phone and Outlook.

Retrieve backed up emails from Time machine in snow leopard after downgrading from Lion?

I installed Lion, but after putting up with it for the last month with problems like: computer crashes, slowing my computer to an unbelievably dismal speed and computer freezes at least once a day, I have now reformatted my hard drive. I have reinstalled Snow Leopard and restored all my settings, folders and applications from a time machine backup.
However, I am now back in my desktop (that's another story as all of a sudden it asked me for a password, even though I've never created one to log in) and on snow leopard- BUT I have no address book contacts and as for my email- well my email accounts appear in mail, but all my emails are lost (sent, received, inbox.... nothing there).
I desperately need those emails back as I run my own business and this has just been a nightmare. I thought that after reformatting and then restoring from a time machine back up life would go back to normal but obviously not.
Can anyone please shed some light on where I would find the folder in my time machine back up to cut and paste back over for snow leopard to show my emails again?
Thanks in advance.
Andrew

I'm on Lion but iPhoto 09 so it might have changed in iPhoto 11
But this is what I see
If yours is different try looking in the iPhoto Help pages for restoring from Time Machine

Why can't I get Back To My Mac to work in both directions between my 2011 Mac Book Air and my 2012 Mac Mini?

Why can't I get Back To My Mac to work in both directions between my 2011 Mac Book Air and my 2012 Mac Mini? The network uses a Time Capsule. Everything works when connecting from the Mini to the Air, but the reverse is not the case, none of the Mini's drives are visible, and the screen sharing option is not available. I've tried the measures already suggested in online articles, everything seems to be configured correctly using my iCloud account. I'm at a loss, any suggestions would be appreciated.

I've now managed to get the service running in both directions, but not in the way I had anticipated. I had to create a second account on the Mac Book Air, this also has administrator privilages, everything works fine when connecting from this acccount. However, this is not the way I would expect to work, none of my documents, applications and settings would be available, unless I laboriously duplicated them to the new account.
Also, I've yet to get the service running from outside my home network.

Under Snow Leopard I used a WD My World NAS to back up my Mac Pro (Mid 2010). When I upgraded to Lion I am unable to access the backup because the NAS does not yet support AFP. I have now bought a Time Capsule and want to transfer the old backup onto it.

How can I recover the NAS back up to put on my new Time Machine.
Talking to Apple Support Adviser was a waste of time on case number 239647273
Any thoughts or pointers?

Keep the old OS around and just kick the tires and test new OS. Apple has a history and habit of breaking support in things like this.
You can use TimeMachine as one level of backup, and even there there were changes with Lion, I would always recommend foremost backup clones of every volume. And clone (SuperDuper etc) can be stored on something like HP NAS Media Server which also was supporting TimeMachine, iTunes - until Apple made that harder and more their own proprietary format.

Cloning as a Backup Strategy
Rather than "upgrade" I would clone the system, and do a clean install, then allow Setup Assistant to import your files.

I want to go back to Snow Leopard 10.6 from Lion. Quicken 2007 is not compatible with Lion.

Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.
