In Mac OSX Lion, I opened Launchboard and deleted an app that I had previously downloaded from the Mac App Store Problem:
I was no longer able to download it, always getting the same annoying message from the Mac App Store software:
“A newer version of this app is already installed on this computer”
After spending hours trying to find the fix that does the trick (and, man, did I try them all: removed spotlight indexing from my HDD, removed launchpad db files, removed various folders and files), countless Trash emptied and reboots, I finally found the fix.
Here’s what worked for me (via stackexchange):
I opened up Terminal.app, pasted the line below, then pressed Enter:
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
A few minutes of waiting, and when it was done I launched the Mac App Store app and.. miracle: I was able to, once again, download my favorite app from the store.
You don’t really need a reason to try out these Mac OSX tips and hacks. But they are fun, probably useful and definitely will get a nice reaction from your friends. They all involve typing some commands in the Terminal.app(each command is followed by the Enter key); if commands start with sudo, you might be asked to also type down your Mac administrator password(which you ought to have set when you first logged to your computer). For instructions on finding Terminal.app and tips on using it, see our great Terminal.app tutorial.
Tip #1. Quickly prevent your Mac from going to sleep
If you are doing something important but not interactive enough(reading an ebook/article or demoing a slideshow to your boss for instance) and get frustrated by your computer repeated attempts to go to sleep, there’s a quick and simple way to prevent this temporarily and without messing anything up: in Terminal, type down pmset noidle
Just remember to type Ctrl+C (^C) in the same window when you’re done.
When your nosey coworkers enjoy peeking on other people’s desktops when they are gone, or you simply don’t want your kids to accidentally erase your soon-to-be-complete Pulitzer story while you were in the kitchen, your mac has the quick and simple solution, one that few people know exists: the screen lock
Enabling screen locking is pretty easy, although hidden where you leaste expected it. Here’s how it’s done:
You’ll need to open up Keychain Access, a utility app that comes preinstalled on your Mac and can be found inside the /Applications/Utilities/ folder. Once there, you’ll open up the Preferences menu (press ⌘, or as the submenu of Keychain Access menu). In the General tab, make sure the checkbox ‘Show Status in Menu Bar’ is checked. A tiny lock icon will appear in the menu, somewhere on the right. Clicking on it will reveal the long awaited option: Lock Screen.
PS. Make sure you know your mac password before clicking on it, because only those who know it will be able to unlock the computer.
I’m not the kind to praise apps, but once in a while a recently downloaded app makes me so happy I need to share it with the world. Today I feel this way about Hyperdock, a currently free beta app (the developer warns us that once it gets final it will cost a small fee – although if you want to keep it free you can probably just disable the automatic updates). To be noted that there’s no hidden reward for me for this tiny review – the developer didn’t contact me about the app(as a general rule I tend to ignore all email I get that promotes web services or apps), I’ve hard about it from a Tweet and decided to give it a try.
Hyperdock installs itself as a System Preferences pane, and replaces the OSX standard Dock with a much more powerful version of it, kind of like a swiss knife of system goodies:
Window previews – when you hover over the icon of an opened app in the Dock, you get to see a small bubble with live preview of the app’s opened windows.
Powerful shortcuts – for all the apps in the Dock, you can configure particular or general shortcuts. Take the default shortcuts for instance – Option+Left click on any of the Dock apps will trigger Expose to show the windows opened by that app. Shift+Left Click will hide it, etc.
Window Management – by far the best feature, allowing to quickly snap and resize windows(Windows 7 style) by simply dragging them to the screen edges, etc. It successfully replaces the $14 Divvy app and adds, on top of that, quick shortcuts for moving and resizing windows.
There are other features listed on the app’s page, but I stop at this for now. I can only hope that the developer will chose a small enough price for the app(I’d expect less than $10, but I’d really hope something like $5) to encourage wide adoption of this pretty great all-in-one app. Give it a try and let me know what you think of it in the comments below.
Everyone knows that multitasking is usually bad for your productivity, and that in order to get ‘in the flow’ one would need to focus on the task at hand and nothing more. Having your app maximized to your screen size might be enough most of the times, but a real full-screen mode(that is, covering also the Dock and the MenuBar) would be even better.
Apparently the next operating system version for your Mac(OSX Lion) will add native support for full-screen apps. But until then, neither of these two options are made easy by the current Mac OSX version.
If you’re in the same place as I am and too impatient to wait for your full-screen productivity boost, I found a temporary solution. An awesome one which, best of all, is completely free(although donations to their developers are welcome)! Continue reading →
It’s a common symptom among new Mac users to be really ecstatic about their new MacBook, praise the speed and functionality, then after a month or so start seeing some flaws; much like in any relationship, where your passionate blind love from the first weeks starts to fade, giving way to more realistic assessments.
Some hard-core Linux geeks will probably miss their configuration files, kernel hacking and source code install. Windows users might miss their favorite software(Picasa, Winamp or Total Commander). I didn’t miss my Windows machine one bit, partly because I got used to other essential Mac software, partly because I use my Windows software from within Windows virtual machines, and mostly because I realized the Mac offers me all the productivity tools I ever wished for, out of the box or for free.
This article lists several essential but frequently forgotten configuration tips that make the most of your Mac. A future article will cover some vitally important FREE (or really inexpensive) Mac OSX software for your daily chores.
Faithful readers might have already read these tips here, on HackTheDay, but I do hope they’ll learn a few new things as well.
Quick question: what is the One and only most essential tool for any productivity fan?
You guessed it – the calendar.
There are many reasons why you’d want to use Google Calendar for your time management: first of all, it’s free; second, it’s online(you can access it from everywhere). Third, it has SMS alerts, which is probably the single feature I use most. The one major downside of Google Calendar has is… being an online tool; a less than perfect user interface, less than instantaneous responsiveness. Luckily, this all is in the past as of today:
Google announced CalDAV support for Google Calendar in Apple’s iCal(version 3.x – on Mac OS X v10.5+ ). In layman’s terms, this means seamless bidirectional synchronization of calendar events. No more awkward emails, no more missed meetings(actually.. this isn’t such a good news, as we all know it – meetings are productivity killers).
Here’s a step by step walkthrough in setting up Google Calendar synchronization:
1. First, you download on your OSX 10.5 mac the setup tool, called Calaboration. It’s in zip format, so you’ll want to unarchive it. Go ahead and run it, entering your Google login credentials, then click Sign In.
If you don’t want to fumble around just to learn the current date, you can display it in Leopard’s Menu Bar, right by the clock, to always have under your eyes.
What I did was to follow TUAW’s tutorial, but here’s a quick summary, just in case you’re in a hurry:
1. in System Preferences, International, Formats submenu. Select Customize date, then chose the format you want, and COPY it (select all, Cmd+C).
2. Press Ok, then from the same window, Customize for the Times part. Move the cursor before the time format, press Cmd+V(Paste). Press OK.
On the 1st of January I had a skiing accident resulting in the injury my right arm – actually my right shoulder. After about two weeks of waiting for the pain to go away, I got the guts and visited a doctor who didn’t think twice before putting my entire right arm into a tight bandage and forbidding me to use my right arm for the upcoming 10 days.
Easier said then done – after all, I’m a work-from-home software developer, right-handed on top of that. Medical leave being out of the question, how am I supposed to get my job done by typing with only my left hand?
Luckily, I managed to work something out, and here’s a couple of the tricks I did for it, just in case they might help other imprudent skiers out there: Continue reading →
I spent the day before yesterday cleaning up my MacBook hard drive and reinstalling anew my Tiger operating system.
Sure, OSX is a very powerful system, but even it gets cluttered after months of intense usage and hundreds of apps installed. So.. nothing like a fresh new install to get rid of all unwanted apps, documents, archives or garbage.
So, if you are a new Apple owner, here’s my list of 9 tips for you to do on a fresh OSX install:
