Screen Sharing using Back to my Mac

I'm trying to use screen sharing for the first time between my 27" mid 2010 iMac and 15" MacBook Pro Retina late 2013 using both OSX 10.9.4 on a local network using Back to my Mac feature. I enabled screen sharing and made sure Remote Management is disabled and also on firewall the screen sharing has allow incoming connections enabled. I also have my Back to my Mac checked on my iCloud settings.
And so I opened Finder window on both computers and on the sidebars from each of the computers it showed the shared devices. So from my Macbook or iMac, I click on the device and then click on the share screen button and a menu popup asking me how i want to connect either as a registered user or using an Apple ID. I selected using and apple ID and it automatically provide a drop down showing my apple id and I click connect but all I get is an error message saying "Authentication failed to iMac" or vice versa.
What am I doing wrong? Is there any other option for me to do screen sharing without using a third party app? Please advise. Any help or suggestions will be greatly appreciated. Thank you.

Thanks for your input. At home, I use a Time Capsule, with the absolute latest firmware, so it should be suitable.
However, I might have problems with the setup? If I turn off and on Back to my Mac under iCloud settings, sometimes I get a message that I should enable NAT/UnPP. Checking the setup of the Time Capsule, the router is in Bridge mode (NAT off). If I try turning on NAT, I get an error in Airport Utility about double NAT.
Any advice on this?

Screen Sharing with Back to my Mac

This little detail is different under 10.7 than 10.6, it has taken me some hours of frustration to sort out by trial and error. I haven't seen it documented anywhere.
When a Back to my Mac user connects to another Mac to share the screen, if the userid used for the sharing connection is the same as the active user on the shared system, then sharing starts immediately upon successful authentication. If the userid used for the sharing connection is different than the active user, then the active user must give permission for screen sharing to start.
One of the consequences is that a sharing only user ID can only be used to start unattended access if the unattended machine is at the login screen.
This is in contrast to 10.6, where any userid can start screen sharing without permission of the active user.

I'm trying to access my home Mac Mini from outside the home using a Macbook. I'm trying to use Leopard's screen sharing using .Mac and no luck, I can't see my Mac Mini outside my network.
At home, I've got the Mac Mini:
(1) running the latest Leopard
(2) connected to .Mac with Back to My Mac running
(3) File Sharing, Web Sharing, Remote Login, and Remote Management all on
(4) Time Capsule with the latest f/w updates running PPPoE to a DSL modem
At work, I've got the Macbook running:
(1) running the latest Leopard
(2) connected to .Mac with Back to My Mac running
(3) File Sharing, Web Sharing, Remote Login, and Remote Management all on
When I'm at home, I can screen share between Macs no problem. However, at work, I can't see my home Mac Mini. I know that it is possible to get through my company firewall because I can get my Slingbox to work at the office.
Suggestions where to start? I'm kinda stuck.

Screen sharing via Back to my Mac

I'm away from home for work.
I have my iMac at home, connected to my internet connection which I know is working. It is on the DMZ on my network so there are typically no issues with blocked ports and the firewall is turned off.
With me I have my Macbook Pro. Both machines are on 10.10.2
When I sign into BtmM on both machines the iMac shows up in finder on the MBP, however Finder says not connected and when i click share screen I get connection failed.
What can I do to troubleshoot this to try and find what part of the chain the issue lies in? I won't be home for another few weeks, but should be able to make changes remotely (the iMac is on, I'm using it to chat to my partner daily and managed to connect remotely via Team Viewer tonight)
TIA

Hey TKarbon,
Thank you for using Apple Support Communities.

After the 10.9.2 upgrade I can't screen share with any Macs using Back to my Mac.

I did the 10.9.2 combo upgrade on a bunch of Macs I manage and now I can't use Back to my Mac for screen sharing on any of them. Does this upgrade mess with the original settings? Any suggestions? Anyone else see this?

Back to my Mac has been unreliable for me (and a lot of other users) ever since the Mavericks upgrade, 10.9.0.
I find that if I turn all screen sharing off, then back on again, remote macs can share my screen. But the fix usually lasts just a few days, sometimes as little as 24 hours.
So everything depends on me remembering to open Sys Prefs and then toggle Back to My Mac (in iCloud) and Remote Login, File Sharing, and Screen Sharing (all in Sharing) in the morning before I go to work. If I remember, I'm able to do screen sharing that day from work. If I forget, I'll get errors when I try to Screen Share via the link that appears under Shared in the Finder sidebar. The link is reliably present in the Finder sidebar, it just doesn't work if I haven't refreshed the Sys Prefs settings.
Hope this workaround is helpful. Wish they had a more permanent fix.

Can't use Back to my Mac on OS X Lion

Hi,
I have upgraded both my MacBook Pro and iMac 27" to OS X Lion, and set up everything as suggested for the iCloud, but I still can't use Back to my Mac function. In fact, on the macbook pro, I can't even see the shared sidebar (after trying several suggestions from the communities from 2008). And on the iMac, I can see the shared sidebar, but there is no option for Back to my Mac. I sware I've ticked Back to my Mac on the Finder's preferences, and everything apparent from the iCloud.
It'd be great if someone can point me to the right direction. Thanks!
Cheers,

Carolyn,
After clicking your link, I think the solution described therein may work -- however, I brought my MBP to the Genius Bar and gave it to them the next 24-48 hours so they could run diagnostic tests, so I am not able to experiment with your solution. I will say this, though: while I was still trying to fix it myself, I DID get the "Allow me to use my Apple ID to reset my account password" checkbox, which I checked, and on the next screen where it lists my various User Accounts (mine, and Guest), I clicked on mine, typed the password (and every conceivable other password I could possibly think of), but nothing worked. Then, when it gave me my security question and gave me a link to "Reset my password," no other window popped up to allow me to perform the reset.
All in all, I'm fairly convinced this is a hardware issue, not a software issue. My system recognizes my HD sometimes, but not others. Perhaps there is something wrong with the cable connecting the HD to the logic board.

How to avoid "share screen request" in "back to my mac"

I tried to use back to my mac screen sharing and it waits for a response to a "share screen request" on the target mac. Is there a way to avoid this? I can't see the value of trying to remotely operate the target mac if someone needs to be there to respond to the "share screen request".

I see that. The problem is that the log in choice only lets me share the screen of my admin account. I want to share the screen of a standard account which is where I do all my work. So I connect to the standard account and then when I go to share the screen I get the "share screen request"
I just tried to log out of the admin account and into the standard remotely and that worked. Strange way to do it but as long as it works I'm fine with it.
Thanks for the response, it did solve my question because it helped me figure out how to do it.

When using Back to my Mac can I use a local printer to print from the remote Mac?

When using Back to my Mac to access an iMac from a MacBookPro all with the latest OS updates may I use a local printer connected to the MacBook to print a document located on the iMac? If so, how? It looks like if I try to print it will all happen on the iMac. Thanks.

PeterFazio wrote:
The problem is that when in screen sharing mode the print command is executed on the remote computer.
I appreciate that, but it will still list the printer in your local location if things are set up properly and if it is you can print, if it isn't you can't, but you should be able to print it as a pdf, transfer the file to your local computer and print it from their.

Is it faster to download files from a remote server or file sharing with Back To My Mac?

I am trying to send somebody a 6GB file using Back To My Mac. I had them set up my Apple ID in iCloud in System Preferences on their Mac and check the box for Back to My Mac. Went into Sharing preferences to check the boxes for File Sharing and Screen Sharing.
From my Mac I then went to that shared computer in the Finder, copied over my file but it's showing that it will take 27hrs to transfer.
Is this normal? And if so would setting up a server for remote access be better for transferring such large files?
Any other mind blowing ideas would be most welcome for remote large file tranfer.

Download history usually will have the link back to the original source location. Assuming that still exists, it's worth a try. When you right-click (Ctrl+click) an item, the small context menu should let you copy the URL of the original source, which you then can paste into the address bar to fetch it again. If the original download required you to be logged in to the source site, you should log in again first to increase your odds of getting the download.

How do I use Back to My Mac with a new Time Capsule if I don't have a MobileMe account?

I just got a new time capsule and I'm trying to set it up so that I can remotely access the files when I'm at work/on the go etc. Now I have an iCloud account, but I don't have a MobileMe account. I do have an @me.com address because I enabled Mail thru the iCloud pref pane and I setup the @me.com email address but I'm still not able to use back to my mac.
I am running the latest fully updated version of lion on the latest model air, working with a 2TB 4th gen time capsule

See the following:

Is it possible to set up Time Capsule on one network and then access its stored data (movies) using Back to My Mac from another network that also has Apple TV to play them?

I recently purchased a Time Capsule to store data at my office. I have an Apple TV at my home that I would like to start using to play my movies. With the storage of the new Time Capsule, I am curious if I can somehow store my iTunes movies on the Time Capsule at my office and then use Back to My Mac to access the TC from my home and then play them via Apple TV. Does this sound possible? We have an iMac at the office that remains on 24/7 connected to the TC.

ATV cannot play movies from the TC, even if it is on your home network.. ATV is a streamer.. it is not a media player.. and the TC is a dumb as a board hard disk in a router.. so it has nothing in it either.
You cannot play movies from ATV without itunes, which streams to the ATV.
If the iMac is running 24/7 then you should be able to connect to the iMac remotely and run from iTunes on that, which could then play movies stored on the TC.. with the following issues.. if you use wireless on the iMac forget it. The iMac has to be ethernet connected as it has to pick up the movie on the library and play it back to the TC to network to your home.
The next issues is speed of slowest connection.
Your download to your home maybe great.. what is the upload speed from your office like??
If you pay for uploads and downloads you will pay for the movie 3x.. first to download it.. second to upload it.. office to net.. and third to download it again.. net to home.. Sorry but it is better to play the movie directly from online itunes store.
If you plan to try and play non-itunes movies over the connection, it won't work.. ATV as stated is linked to itunes and cannot play movie files.
Overall this sounds like you need to think it out a bit more.

How can I use Back to My Mac using my Apple ID

I'm having problems accessing my other computers using Back to My Mac. I've gone into System Prefference>iCloud and turn on Back to My Mac on all mey devices. I've have also gone into my router settings and opened the appropriate ports. I can see my other divices in Finder. When I go to connect I am given a choice of "As a registered user" which works sometimes and not others and also "Using an Apple ID" when I choose this option my Apple ID appears in the drop down box (and is the only option in the drop down box). Howevere, when I click "Connect" it comes up with Authentication failed to JQ MacBook Air.
Any Ideas

Hi,
Are they both using the same iCloud account/ Apple ID?

I want to use Back to my mac. When I try to turn it on, it says "Back to My Mac may be slow because more than one device on your network is providing network services. Turn off NAT and DHCP on one of the devices and try again." How do I fix this?

Not sure if I am doing this right. This is my first time in the support community.
I imagine what I put in my heading was supposed to go in here.

Does anyone know how I do this? I contacted my ISP (Telus in Canada) and they did not know anything (not that they usually do).

Why do ISPs insist upon making things so difficult for their customers?
If you cannot get them to understand that you would prefer to use your own router over their piece of cheap junk, perhaps the information in the following will be useful:
http://keithbalomben.wordpress.com/2012/03/29/telus-actiontec-v1000h-hacks-and-i nformation/
Scroll down to DHCP Settings
You will need to log in with proper "technician" credentials. They are provided in the above link as
Username: tech
Password: t3lu5tv
... but these may or may not work. Try it, and if you cannot get anywhere at least now you know what to ask Telus to do in return for your business.

Use "Back to my Mac" for off-site TM backup?

Can I use "Back to My Mac" for a Time machine backup.
I'd like to setup a remote hard disk on my parent's iMac so I can backup remotely. I'll do the same for them on this site. Unfortunately, I suspect it's not that easy yet.
We both have 1Mbps upload speeds so it'd be fine for backup of changes, but for the initial backup we'd have to move our laptops to each others' houses.

Anyone know?

Since last update (today) I get invalid password when trying to use back to my MAC, password works everywhere else

since last update (today) I get invalid Apple ID password when trying to use back to my MAC in Icloud app on my MAC, password works on all my other devices. GLITCH ?

Try going to the Apple ID page on your web browser
http://www.apple.com/support/appleid/
and try to either retrieve or reset your password
(obviously you had to be able to successfully log in to be able to post here)
I was finally able to log in through my system preferences after about three or four hours. I ran a disk utility to repair permissions and restarted and it seemed to work ok.

Hello, I've installed Lion but now it says I can't use the Cloud as I need the Apple ID Password to use Back to My Mac. I've obtained several new Apple ID passwords which work ok on my phone but doesn't seem to be the password it's looking for?

It's probably looking for the Apple ID & Password you used to purchase Lion, or ML as the case may be.
Thse are the Mountain Lion forums, is that what you meant?
