Also, dialog boxes finally react to pressing ENTER (to press the highlighted/default button) and ESCAPE. Lion solves a few of them: For example, most windows can now be resized on any edge, not just the bottom right corner. On the other side, it has a GUI that looks gorgeous and well designed, but has some horrible Usability issues. On one side, it's UNIX underneath so I get a terminal that gives me everything I really need. ![]() I have the somewhat controversial opinion that Mac OS X has major usability issues. Snow Leopard was still way too slow even on the maximum setting, while Lion finally remedies this. With 2 monitors and 4096 pixels vertical resolution, I want fast tracking. In the Mouse settings you will also find a huge improvement: The tracking speed was increased. You can disable it in the system settings by unchecking the "Scroll direction: natural" box. This is consistent with how iOS works and works well on a (Magic) Touchpad or a Magic Mouse, but is downright weird on a Wheel Mouse. One of the hot topics was the fact that Apple reversed how scrolling works - moving the wheel down now moves the screen up. Installation took about 40 Minutes on my Mac Pro (from DVD) and about 70 Minutes on my MBP (from Hard Drive), not including the 3.5 GB Download from the App Store. For the MacBook, I updated from Snow Leopard version, while I did do a fresh installation from DVD on my Mac Pro. I own a Mid 2010 MacBook Pro (13", Core 2 Duo 2.4 GHz, 8 GB RAM) and a Mid 2010 Mac Pro (1 CPU, 2.8 GHz, 12 GB RAM). Naturally, I immediately installed in on both machines. If you learn to use it now, it'll be much easier to diagnose any issue your Mac is having.So the long awaited and long debated Mac OS X 10.7 Lion came out today. It helps you gain insight into many hidden but invaluable facets of your computer-from CPU and RAM usage to disk usage. It also helps you to block apps from "phoning home" without your knowledge.Īctivity Monitor is one of OS X's hidden gems. It can clue you in to which of your running applications are accessing and sending data to the Internet when you might not be expecting and also help you to see if unexpected applications are sending data out when you don't want them to. If you're curious what kind of data an app is sending and receiving, the free app Little Snitch monitors network traffic on a per-application basis. This is very useful if your internet subscription has a data cap-you can see which apps are using the network most, and use them less if you're nearing your cap. It shows total network activity across all apps, and processes that are sending or receiving the most data. The network tab will display information on network traffic, regardless of whether it's wired or wireless. In the event a disk intensive application is running, which may be a system process or a user added application, such as a database, the activity will vary along with the activity of the offending process. If your hard drive is running out of space, it can get even worse: the system must go through a process of hunting for free blocks on the drive while simultaneously deleting any temporary files it can in the process. If your system is short on RAM, as discussed above, the excessive disk activity could be caused by swapping memory contents to the hard drive and back. Pay special attention to "Data read/sec" and "Data written/sec." What's causing the disk usage? Sometimes it correlates with CPU usage, and some apps and processes are heavy on both, like when converting video, audio, or Spotlight's mds Pay close attention to how often your system accesses the hard drive to read or write data. Having enough RAM is crucial for system stability, but your hard drive is almost important. On the top right there is a "Search Filter" box which lets you search for a specific process. Click the column title once or twice to change the order. You can also sort the list of processes by any of the columns in ascending or descending order. Expand the "Columns" option, choose the ones you want to view, and they'll appear in Activity Monitor. It's possible to view additional columns by going to the "View > Columns" menu. All the processes are listed together with a more details in each column. Some applications are easy to spot, while others are background system level operations you don't normally see. Notice how many items appear in the Process list, even when you're just staring at the desktop doing nothing. The main pane shows both a list of both open applications and system processes. ![]() The main screen of Activity Monitor is divided into two sections: Launch the Activity Monitor app by going to "Applications > Utilities > Activity Monitor," or just type "Activity Monitor" into Spotlight.
