After the near miss I had in losing a considerable portion of my personal digital library I decided to do something about it and look into a cloud based solution for keeping my files safe. I’m still using Time Machine locally to back up nearly everything, I just wanted a final line of storage just in case. I’ve been using DropBox for years for my documents and miscellaneous files. I have several Google Apps for Business accounts that store my emails and shared docs and spreadsheets. The code I write is versioned and stored in GitHub . For the most part I live off the cloud already, the only thing missing was my large collection of family photos and videos, which totaled nearly 140GB. iCloud is cool and all, and I love the way it keeps my little iPhone photos synced, but at $100 / year for only 55GB, this is a pretty expensive solution. I looked at a variety of different cloud backup solutions and found them to be ill-fitted to my needs. While many of them have plenty of capaci...

As I wrote last week, the SSD upgrade for my Mac Pro went very smoothly. There were two important things I found out after I started reading the comments from that entry: An SSD is a good performance upgrade but the OWC Mercury Accelsior_E2 provides incredible performance. Though quite a bit more expensive than a standard SSD, if you want the absolute best performance for a Mac Pro you may want to consider it. At 820MB/s it is over 5 times faster than the SSD I just installed. Hat tip to Eytan for pointing this out to me. After adding a 3rd party SSD to your Mac, you need to investigate TRIM support. Derek brought up the issue in the comments and I spent some time investigating it. What is TRIM? TRIM is effectively a garbage collection model for SSDs. There is some great information on it on Wikipedia’s TRIM entry . The bottom line is that without TRIM enabled the performance of an SSD will suffer over time. This is something you’ll want to address. I contacted Crucial tech...

Mac Pro circa 2008 I bought my Mac Pro 5 years ago and other than the hard disk failures I just had with my add-on drives, the machine has been rock solid. I’ve kept it up on every version of OS X that’s been available and it runs Mountain Lion like a champ. Even though my Mac hasn’t slowed down with age, it feels relatively slow ever since I added my new 15” MacBook Pro with Retina display to the mix. Between the 16GB of RAM, stunning display and ridiculously fast SSD, the new MacBook Pro seemed to run circles around the larger Mac tower. Upgrading the processors didn’t seem reasonable. It already has 12GB of RAM and for the way I use the machine that provides plenty of headroom. The one area I figured could see dramatic improvement was by swapping out the 320GB boot disk with an SSD drive. This was the route I took. Finding the Right SSD I did a lot of reading on SSDs, looking at Amazon reviews and finding guidance from a variety of different sources where I primarily f...

It had been a long couple of months. We’d been working furiously on the launch of EasyGrouper and were just a few days away from having it go live. As I sat in my home office working on my new MacBook Pro I heard a deeply disturbing sound coming from my older Mac Pro tower a few feet away:    ZZZZ-click     ZZZZ-click    ZZZZ-click That’s never a good sign. My Mac Pro is my main home machine and runs a lot of stuff for me. It’s got a 320GB main drive (“BootDisk”) running my apps and working documents, a 1TB drive called “BigDisk” that contains my family photos, videos, music, etc. and another 1TB drive called “Backup” for... you guessed it... backups. I tapped the keyboard to wake up the screens and could see that the icons for my drives were all on my desktop when suddenly the BigDisk icon vanished and OS X gave me an error message that said I had not ejected the drive properly. Not good. My Mac could no longer see my BigDisk internal d...

We mourn the loss of famous people—our entertainers, our leaders, our athletes—even though we never got a chance to meet them in person. They entered our lives through popular media and became part of it. We would watch them act or sing and it would engage us. They would speak about the important challenges we face and we would be inspired to address them. We would watch in awe as they performed incredible feats of skill, wondering how anyone could pull that off. When one of those famous people die young, it's notable. That small window in our lives that they occupied goes dark and we miss them for a time. Steve Jobs was different. He wasn't an entertainer, yet he could capture the attention of the public and engage us. He didn't give many speeches, but the few he did were inspirational . Though he was not the classic business CEO he created multiple businesses that enjoyed extraordinary financial success. While these are all great accomplishments, it's not the ma...

I've been playing with Lion fairly steadily now since its release and have some initial impressions I'd like to share. Gestures The changes to the gestures in OS X are dramatically different. I can deal with the change to scrolling direction on a page (up is down, down is up) - that's really not that big of a deal. After less than a week I've completely adjusted to it. You can switch it in settings if you like, however you are better off just adjusting to it if you are exclusively a Mac user since it matches up with how actual touch screens like the iPad work. Apple wouldn't be making a change like this just for consistency, I believe it's to prepare Mac users for the future when a hybrid device that is a merger of iPad and Mac is released. What is a big deal is that the default behavior for going back in a browser (three-finger swipe left) is changed, now it's two fingers and only works on Safari (not Chrome). I'm hoping I can get this to work in C...

Like many Mac users I am in the process of upgrading my Macs to Lion today. With 8 Macs in our house downloading 3.7GBs of installer seems like a huge waste of bandwidth. You only need to purchase the upgrade once for all of the machines you own or control so here's a technique that may help you only download Lion just once: 1) Purchase Lion on one of your Snow Leopard Macs The download is about 3.76GB so depending on your connection speed it may take a while. You'll need to be current with Software Update if you aren't already. 2) Once the download is complete you will be presented with this screen: 3) Do not click Continue! Press Command-Q (or quit from the menu) instead 4) Open Finder and navigate to your Applications folder You should see the installer with the Lion icon titled "Install Mac OS X Lion". Copy that 3.76GB file to portable media device (like a Flash drive or external hard drive). 5) Copy the Installer application to the Applications fol...

As I wrote up my last blog post on Skype alternatives I started seriously looking at iChat again. Since I had been using Skype for my video chats and Adium for my IM communications, iChat never seemed to have that little blue orb beneath it in the dock bar to indicate it was running. When I first switched to Mac over three years ago I played with iChat and relatively quickly dismissed it as a cute toy. The cartoon bubble discussion was cute but not compact enough for my relatively heavy IM usage. The video chatting was cool but after playing with the effects button and carrying on a video chat while riding a moving roller coaster I quickly concluded that this was a fluffy consumer novelty and moved on to other applications for my business needs. Researching alternatives to Skype changed all that. The more I played around with iChat, the more I learned about some interesting features, especially if the people I was communicating with also had iChat available to them. More and mo...

Microsoft has agreed to acquire Skype for $8.5 billion in cash. As a long term Skype user I've had Skype loaded on my Macs for years now. It serves for video chats with my family and business associates and also as my desk-bound IP telephony device. This model has worked well for me. By combing a couple of cool AppleScripts with Launchbar I can call people without my fingers leaving the keyboard. So if everything works so well, why would I need an alternative? Skype's Mac Client I was more than a little concerned when Skype released their last Mac client and it was, well, not very good. Skype's never really been a company that embraces the Mac user interface well, though version 2.8 is serviceable from a user experience standpoint. With the announced acquisition my confidence in Skype putting any money into "embracing and extending" the Mac client in a way that makes dedicated Mac users happy is... well... compromised. Microsoft My confidence in Microsoft...

When I bought my new MacBook Pro I used the applications I had running on my previous MacBook Pro to help me determine what I would need in terms of horsepower. It was an interesting exercise, mainly because it gave me a good sense for all of the things I need my Mac to handle throughout the day. I'm a software developer and do some of the development for SharedStatus , so my needs are a little biased towards that. I've broken down what's running on my Mac into two sections, Basics and Development. To give some perspective on how many apps I have loaded up as I write this, here's a snapshot of my current Spaces window zoomed out: I've always been fascinated by these types of lists because it helps give people exposure to some apps they may not know about. Here are the ones I nearly always have running: Basics Safari I love the speed of Safari and this remains my default browser. Nice and fast, Safari does have a tendency to crash on me if it's been run...

When I packaged up my old MacBook Pro for my daughter I did a quick wipe down of the machine and found that though it was three years old it had very little visible wear and tear. The keyboard and palm rest areas were in perfect shape and there were no dents in the aluminum case. Though the white power supply and cords were a bit dirty a quick wipe down with a damp cloth had them looking like new. About the only thing that made the machine look used was the outside of the case. As I had slipped it into my bag or carried it in my hand, objects like my watch band had rubbed against it and put a series of small scratches all over the outer shell. They were purely cosmetic but annoying nonetheless. I’m determined to treat this new MacBook Pro with a little more care and as a result started searching around for a protective shell case for it. I rationalized that this would help maintain the resale value of my Mac in the unlikely event I decided to sell it or—more likely—it would look l...
