Mac OS X: upgrade to Lion?

Before upgrading to lion, you should not only refer to the parameters of the hardware platform supported by the apple official release of lion and its novel features (refer to: Mac OS X LION: lions
), Software compatibility is also an important aspect. Because lion has abandoned support for Rosetta. Rosetta is a successful tool for Apple to switch from the PPC hardware platform to the Intel Platform. It allows users to run the old PPC-based coding software on the Intel Platform's new computer, this provides the maximum compatibility for everyone. Since 10.4 to 10.6, But lion gave up this compromise, Apple may think that it has "done everything right. If your daily use depends on some software, you must check

Check whether the current version is PPC encoded. If yes, you cannot use it in the new system. Whether the upgrade is determined depends on whether it is replaced by other software, are you willing to invest in upgrades. In addition, some software may still have large or small problems in the new system even if the encoding method is supported. This requires you to carefully check the compatibility list updates of each software. Currently

Each software developer must test their software compatibility in the pre-release version. I believe that soon after the official version is released, there will be an official release of each software.

Before that, we may want to check it out first. Check the coding method of the software. The most common methods are as follows:

• The simplest is to select an application in the finder.Program, Use get info to view the information. If it is universal or
  Intel, so we can. If it is a PowerPC, it won't work.

• In addition, you can use system profiler to view the information. In about this mac, select more info.... On the left side of the system profiler window, select software under the Software category. Depending on the amount of your software, the system may take several minutes to list all the software in the current system on the right. As shown in the figure, you can find the software encoding method in the kind column. This method is comprehensive and can eliminate all the software in the system.

• You can also find the code of the running software in activity monitor, as shown in figure

In fact, when the new system was just officially released, there was really no need to update it immediately for common users. Everyone was prepared according to their own needs, in addition, 10.6 of technical support will last for a period of time.
