Slack won’t open or you need to clear your settings.

Last week I found myself in a awful predicament. for Mac would not open and would hang when trying to load a Team.  I searched the Internet and then looked for the files that held the Slack Settings myself in all the usual places (~/Library/Preferences, ~/Library/Application Support, etc.).  After not having any luck I even at one point tried App Zapper to see if it could find the settings folder … No Luck!

After not finding anything I had somewhat decided that the only thing to do was to contact support.  Support didn’t help a lot and told me to go into the app and click Help -> Reset Local Cache.  This is a great tip for most things but there was one problem.  The app would not stay unfrozen long enough for me to click on Help -> Reset Local Cache.

I told the guy in support this was the case and didn’t hear back from him because of the long weekend.  I finally ended up just creating another user profile and fixing the issue that way (which sucked but I was due a format / reinstall anyway so I went ahead and did that while I was at it).

Tuesday support finally got back to me and had a solution that does in fact work. That file that I couldn’t find is in fact located in ~/Library/Containers.  So while this post doesn’t help me I thought maybe it might fix someone else’s problem(s) that wanted to reset their slack settings and could not.  Simple go to the ~/Library/Containers folder and delete the com.tinyspeck.slackmacgap folder.  This will reset your preferences and any Team Data you have in Slack.  Hope this helps someone else.

10 great iPhone Apps for almost any user

When I give training classes on iPhone’s and iPad’s for business the number one question I get asked is what apps I use for my iOS devices (iPhone and iPad). After getting this question several times a lady finally said “Why don’t you give us a list.” and so this blog post was born. The 10 Apps that I use the most that others would find useful. Don’t get me wrong I use several other apps, but these apps are the ones I find to be the most productive for almost any user.

Will hundreds of thousands of people be without Internet come July?

For those of you following the recent news release saying that users could lose their Internet:

I thought I’d give you some details of how DNS works and why you would/could potentially lose your Internet access. Let’s start by explaining what DNS is … Domain Name Services (DNS for short) is basically a telephone book for computers. In simplest terms, it takes IP Addresses ( which are numbers that are easy for computers to work with and matches them up with URL’s ( which are website names easy for people to work with. This is done so that when you want to go to a website you don’t have to know what IP address the website is hosted at but just the name itself. DNS does that work for you.

Understanding and Creating User Quota with Dovecot 1.2+

The dovecot wiki for 1.2 was an afterthought in my opinion. It seems they were already starting to focus on 2.0 and just kinda threw 1.2+ (The version that comes with debian squeeze) into the Debian 1.0/1.1 wiki located at I read through this a bunch and decided I’d write a little tutorial about how to setup a user quota using MySQL and Dovecot. From what I’ve seen on the search engines this is something a lot of people are looking for. My mail server setup is based on the configuration from which provides a great foundation for setting up a stable PostFix/DoveCot/Amavisd-new solution. So all I needed was a few small things to add to make the quota system work (even with the client reporting the quota to the customer).

Roundcube for your Debian Squeeze Mail Server

I am a big fan of the “ISPmail tutorial” for setting up mail servers. It works pretty good and is usually pretty detailed and to be honest, I’ve been using it for years to configure my mail servers under Debian Linux. After migrating to squeeze the first time, I just used the tutorials “Migrating from the Lenny” section to update my server.

I’ve always loved roundcube as well and even in the early days found myself stopping the tutorial and configuring my own copy of roundcube. The new tutorial actually makes mention of roundcube so I was excited when I got the opportunity to configure a new mail server. The only disheartening thing was that the mail server tutorial for squeeze isn’t finished to the point where it talks about roundcube configuration. I’ve set it up many times so I thought I’d try to use the generic debian apt packages and go ahead and document my steps along the way. Here we go…

Securing an external (flash/usb) drive in mac OS X

Being the typical nerd that I am, I tend to have several different Thumb drives and some of them have confidential data on them. I try to never loose them but let’s face it, sometimes those little critters just get lost. The question is do you really want the data you keep on those drives out in the hands of the general public? I have a few different drives. A few I just use to throw junk on and transfer between computers, but I do have drives that I keep confidential data on that I use as a backup from my computer. So I faced the issue of if that drive came up missing not freaking out that my data is in the hands of someone who might use it maliciously.

Dell 3115cn Scanner Support for OSX Lion

Several requests about getting the scanner working on their OSX Lion install with the Dell 3115cn have made me write this post. Some have had trouble getting it to work through SMB. So here goes instructions on how to get your scanner working with OSX Lion via FTP. Please note that this doesn’t actually work the way one might first expect. When most people think of connecting a scanner to a computer they think of the computer doing the work by prompting the scanner to do the scanning. This isn’t actually the case with the 3115cn. It has the ability to do a scan server which is how we will set this up.

Dell 3115cn on OSx 10.6+

Many people have contacted me about a 3115cn printer driver for OS X 10.6+. Unfortunately Dell hasn’t released a driver for it, and the old installer packet required Rosetta even in Snow Leopard. On a developer box I installed the driver and then created an install for the 3115cn to work on OSX Lion. I hope I have everything included, but please let me know if you are having trouble with the installer package.   The package is older so it does require you to restart your computer on install.  It also might ask you to repair the printer when created.  Just do it and it’ll print fine.

Getting Dell 5100cn to work with OS X 10.7+

OS X 10.7+ Driver for Dell 5100cn. With the discontinued support of Rosetta the Dell 5100cn OSX driver fails to load. This was always an issue in Snow Leopard as well because I really hated installing Rosetta just for a printer to be installed.

**Update – After installing this on El Capitan it will ask you to repair permissions the first time you print but it does work. **

Getting Devonthink Pro Office 2 to work with Snow Leopard

I looked all over the internet and found several articles and posts about how Devonthink wasn’t supported with snow leopard. This is frustrating to me because for the most part it should work just fine. So I started investigating how to get it to work and I’ve got about 80% functionality now. Here is what I did:

Install DevonThink Pro Office from download on the website. After downloaded drag to the applications folder as normal. Then open Devon Think. Upon the first open it will ask you if you would like to install Devon Think’s Add-on’s and Extras. Uncheck all of these and then devonthink will open. Go ahead and enter your license in and test to make sure you can open a few different databases if you have them. This was all working great so I decided to see if I could take it step further.

For the most part, I use Devonthink to take scans of papers on my desk and place them into searchable groups. Its a giant filing cabinet on the computer for me. I like this process to be fast so I turn off the OCR part and then manually OCR and organize from the inbox at the end of the day. But without Abbyy FineReader installed I have no way of doing the conversions to OCR nor are the options even there on the context menus. So the next thing I tried is to install the PDF Services Scripts. This worked without a hitch. I then restarted DevonThink and installed ABBYY as the only option in the Install Add-ons (Under Help Install Add-ons). I don’t really use the sorter and turn it off anyway so I didn’t need to install it, and I also don’t use the Mail built into OSX so I didn’t install that plug-in either. After this I went back and installed Application Scripts and DevonThink Pro Scripts. Both worked but the program does hang when trying to print a pdf directly to devonthink from Safari. I can live with this.

I haven’t tried scanning from my s1500m yet but this is next on my list. I hope this helps someone get to your files at least for reference purposes.
