ScreenSharingMenulet hits 2.0
ScreenSharingMenulet is a free (donations requested) program which I've mentioned before that runs in your menu bar and gives you access to computers for quick access to screen sharing. My success with Back To My Mac was "spotty" at best until I started using the DynDNS service, port forwarding, and DHCP Reservations to get 100% reliable screen sharing sessions between my home and work computers. (It's not nearly as complicated as it sounds. Most of it is just one-time configuration which will then make things easier every time you do it in the future.) This does not require a subscription to MobileMe or involve any cost. DynDNS hosts don't appear in the Finder like Back To My Mac hosts do, which is where ScreenSharingMenulet comes in. Click on the menu bar icon, type in the DynDNS hostname (check the box to "Add to My Computers"), and voilà! You're connected as easily as you always thought Back To My Mac would be, but never was. ScreenSharingMenulet has just released a new version 2.0 which has preferences to show/hide Back to My Mac Hosts and show/hide local IP addresses. It also fixes a few bugs. One change that people may not like as much is the removal of the "Recent Hosts" submenu, but frequently contacted hosts can easily be added to the "My Computers" menu by checking a box when initiating the connection. A few other minor changes were also made. Even if Back To My Mac worked consistently and reliably, I would still prefer ScreenSharingMenulet for initiating the connection because it's easier and faster to reach from my menu bar than going through Finder.
Use DynDNS for better success with Back To My Mac
Many folks were excited when Apple announced Back to My Mac as part of MobileMe. Being able to remotely access your Mac from anywhere sounded like magic. We're used to products from Apple that "just work" but for most people most of the time, Back to My Mac "just doesn't." To maximize your chances, you're supposed to use a supported router, but even that's no guarantee. At home I have an Airport Extreme Base Station (Wireless-N), and at the office I have an Airport Extreme Dual-Band model. I don't think it's possible to get a "more compliant" setup, yet I still can't get it to work most of the time. Under the adage "nothing ventured, nothing gained," I took a chance and signed up for a free account with DynDNS. DynDNS gives you a free hostname which will go to your computer even when your IP address changes. There are scads of DynDNS domain names available, but for the purposes of this example, let's assume that your domain name is imac.homeip.net.
Experiencing the iChat woes? Try the Connection Doctor
Now in its fifth iteration, iChat has gained a host of features as it has matured. However, the addition of new features has brought on new complexities and requirements, including both hardware and bandwidth issues. For instance, at the time of its release, iChat 3 users needed a minimum of a Dual 1 GHz G4 and a 384 Kbps Internet connection to initiate a four-way video conference on iChat 3. Photobooth and Backdrop effects, which came along in iChat 4, call for a minimum an Intel Core Duo processor. And then, of course, one must climb the proverbial firewall. Fortunately, there's iChat's Connection Doctor. Besides telling you what your system is capable of (for example, screen sharing, multiperson video conferences and video recording) and the audio and video quality of your video chat (resolution and frame rate), the Connection Doctor can also tell you if networking issues (i.e., a firewall or port issue) are the source of your video conferencing maladies. To launch iChat's Connection Doctor, click on "Video" on iChat's menu and then select "Connection Doctor." It's just what the doctor ordered.
Mac 101: Add Screen Sharing folder to Dock for quick access
More Mac 101, our series of tips and tricks for novice Mac users. This is really two tips in one. The first is a fairly basic one that new Mac users might not know: you can drag any folder to the right-hand side your dock (to the right of the faint-white lines which separate the Trash from applications). When you first set up an account, the Applications, Documents, and Downloads folders are already there. The second is a "news to me" tip: did you know that when you connect via screensharing to different Macs, a file is created in your home directory at ~/Library/Application Support/Screen Sharing/? These files can be used to reconnect to those machines simply by clicking on them. This means that you can launch Screen Sharing without having to switch to Finder, locate the machine, and then click the "Screen Share..." button. If you screen share to a different Mac, the .vncloc file will automatically be added to that folder. Just drag the folder of Screen Sharing shortcuts to your dock to make it into an easily-accessible Stack. Using the Finder does have one advantage: if a computer is not available (if it's powered off or asleep) it will automatically disappear from the "Shared" section in Finder. The files in the Screen Sharing folder will still be there, so if you are having trouble connecting, you might check Finder to make sure that it still "sees" the computer you are trying to reach. Henrik Nyh also suggested putting VNC shortcuts in a Stack in the dock, and he adds the notion of picking some suitable icons for them. Check out his rundown here.
Using DHCP Reservations to overcome Bonjour woes
I love everything about my MacBook Pro, but for some reason it does not like to share its screen. It appears under the "Shared" section of the sidebar in Finder, and file sharing works perfectly, but for some reason screen sharing won't work. The "Connecting To 'MacBookPro'" panel will pop up and then disappear a few moments later (as if it is about to connect), but at least 90% of the time no screen sharing window appears. Fellow TUAW writer Aron Trimble suggested that I go into Finder and try "Go > Connect to Server" and then put in "vnc://10.0.x.x" (where 10.0.x.x is my MacBook Pro's IP address). That worked immediately, and every time. This confirmed that it wasn't a firewall setting (Screen Sharing is explicitly on) or trouble accessing the MacBook Pro over the LAN (file sharing already worked perfectly). For some reason the screen sharing connection was just not being made over Bonjour. The only drawback to this direct-IP method is that my network, like most, uses dynamic addresses with DHCP, meaning that the IP addresses change from time to time, especially on a network with multiple devices which are not always turned on. My first thought was to create a static IP for the MacBook Pro in System Preferences > Network, but then I realized that my office LAN uses IPs which start with 192.168.x.x. I could create a new network "Location" but that would also involve manually switching it back and forth, or using a third-party program. What I really needed was a way to make sure that my MacBook Pro is given the same IP every time it connects to my home LAN. Fortunately, Apple's Airport Extreme will allow me to do just that using DHCP Reservations. A DHCP Reservation tells the Airport Extreme to reserve a certain IP address for certain computers, as determined either by a "DHCP Client ID" or the computer's MAC address. A DHCP Client ID is easier to remember than a MAC address, but the MAC address will never change unless you swap out the logic board or Airport card of your Mac. I'll show you how to set it up using either method.
Fujitsu's Frame Zero concept knows no boundaries, no bezels
It's always fun to see what big tech companies think the future will be like, and for Fujitsu the future is Frame Zero. It's basically a system of bezel-free devices that can all wirelessly connect and share information, not at all unlike Microsoft's Mobile Device Collaboration patent application we took a gander at last year. The concept video below shows both a sort of tiny mobile PC joining forces with an eminently breakable looking cellphone to share information cross-screens. But, it goes further, with talk of the larger of the two acting as a sort of alarm clock that, when you swat at it in the morning, checks your body temperature to determine how well you slept before barraging you with e-mails and financial reports. Just what you need first-thing in the morning.
Skype 2.8 for Mac gets update for Snow Leopard
Skype 2.8, with hot fixes for Mac OS X 10.6, is available for your downloading pleasure. It's a micro update of the summertime release of Skype 2.8; the version number is now up to 2.8.0.722. The release date is listed as September 17. Version 2.8, originally released in July, included features like screen sharing & improved audio codecs that had been around in the Mac beta and the PC version of Skype for awhile. Version 2.8 also included Skype Access, which is a pay as you go public Wi-Fi service based on the Boingo network. This latest update adds a bunch of fixes for Snow Leopard. Skype has very detailed release notes if you are so inclined. Skype is a very popular solution for free audio and video chatting and instant messaging. The app also provides many paid services to allow you to call cellular and wired phones anywhere in the world at low rates, and to forward calls to your chosen phone when you are offline.

World's dumbest crooks: the saga continues
Yesterday we told you about some crooks that broke into a house and made off with a couple of Macs and a PC. We recounted how the victim used his replacement MacBook Pro to screen share with the stolen device, and even watch as someone filled out an online form to find a job, displaying an address, social security number and phone number. Well, the crooks are still at it, and seemingly oblivious to the consequences. Last night, I heard from 'Jim' the victim, and he said he was connected again to his laptop, but no one appeared to be home. He saw an unfamiliar jpeg image on the desktop, and you guessed it, the alleged perp had proudly taken a picture of himself with the built in iSight camera. 'Jim' grabbed the pic, and has now forwarded it to his local police department. It's kind of amazing that the crooks would know enough to grab a pic from the camera, but not realize they have left the Mac wide open to the features of Back to My Mac. Hopefully, the police will get in gear, and rescue the stolen computers, and grab the perps. Meanwhile, 'Jim' is cautiously considering getting back into his Mac and erasing any files with personal info on them. He just doesn't want to get caught and spook the thieves. We'll keep you posted.
An incredible stolen Mac story without a final chapter
Update 2:30p ET 9/1: We've heard more from the theft victim; see the latest news on this crime story here. We're getting our share of crime stories lately, and today's is really a jaw dropper. I'm going to be sketchy on details and locations because there is an investigation underway. Here's what we have so far. An East Coast man had his house broken into with 2 Macs and one PC stolen, along with some other household items of value. One of the Macs was a laptop, and our victim bought a new MacBook Pro to replace it, and used a Time Machine backup to restore all his files. The crime was reported to police, who said they had no leads, but there had been a string of similar burglaries in the area for quite some time. When our victim (we'll call him Jim) sat down at his replacement laptop last night, he saw one of his missing computers come up as a share via the Back to My Mac feature of MobileMe. He clicked on the share, and explored the files of his stolen machine. You can guess what comes next. Taking a chance, he clicked on screen sharing, and saw that someone was using his Mac, checking lottery numbers on a web page. Jim didn't want to take control of the Mac, so he just watched, fascinated. Later, when activity on his missing computer stopped, he went to the network panel and grabbed an IP address, and took a screen shot of it. This morning, he saw someone applying for a job online using the stolen laptop, and Jim now has the Social Security number, address and phone number used on the job application. Jim speculates it is possible the machine has been sold to someone and that is who was applying for the job. Or it could still be with the crooks. He's contacted the police, and we don't know how this saga ends yet, but we'll let you know how it all works out. So far we've got a pretty smart victim and some really dumb crooks. Jim says he is sure he'll be renewing MobileMe when it's time. Details at 11. [Thanks to 'Jim' for sharing his experience with all of us]
Screen sharing is caring: Skype 2.8 goes gold
The good folks at Skype have just gone gold with the 2.8 update (link) (previously in beta) of the popular VOIP client for Mac OS X. As TUAW previously noted in the beta release of 2.8, the update brings with it support for screen sharing and Skype Access, the company's pay-as-you-go Wi-Fi service. With screen sharing support, you now have the ability to share presentations, documents, and slideshows with that Windows friend of yours that you would otherwise ignore -- you know, that guy whose PC tower is so well-decorated with neon lights that you'd think you went to a rave when you walked into his room. Yes, that guy. A host of other features are also included in the update. Improved chat management provides the ability to sort and prioritize chats, a quicker way to add people to chats, and mood messages for chats. Larger profile pictures (now up to 256x256 resolution) are now supported; and if you want to hide your profile pics from incoming contact requests, this is now supported as well. And for those of you that can't keep track of who you're talking to, or what you last talked to that person about, you are now given the luxury of a notes field for each contact. Skype 2.8 is available for download (link) at the Skype website, or via the "Check for updates" option within the Skype app.
