Lion Boot Disk

After listened to some podcasts about Lion installation, I decide to test out the DVD disk I made while I installed Lion to my Macs. According to the information I received from all the resources, the bootable disk should be burned from Disk Utility tool. Therefore, I am not sure if the DVD I burned directly from Finder to DVD is bootable or not. I have to test it out by restarting my Mac.

It approved that my way to burn dmg file is not the right way. I could not find out my DVD. During the restart process, the boot selection is turned on when the option key is pressed. However, I found that there was two disks to boot: my Mac Lion HD and a Recovery HD. I have never seen this Recovery HD before. I think that Lion creates a boot disk in my HD. Since there is no disk available for Lion installation, there should be a way to boot in case of HD repairing. Now I recall that Snow Leopard recommends to use the original disk to boot and to use the Disk Utility tool to verify and repair HD.

To verify the Recovery HD is really a Lion boot disk, I started my OS from the Recovery HD. It is a Lion boot HD. Here is the entrance of the startup:



Here is the menu item of Utilities:



Here is the Disk Utility. As in the window, Disk 1 contains a Mac OS X Base System:



I copied my Lion dmg file to my desktop and then followed the correct instruction to burn my Lion dmg file from Disk Utility app. Now the new DVD is bootable. Here is my second try of restart with boot disk selection:



I verified the DVD disk by selecting it as start. It took several minutes, maybe 10+ minutes to load start files. The DVD media is just too slow to start up. That's why Apple does not like optical disk at all. It is just like floppy disk ten years ago. It is time to retire DVD/CD media.

After all these tests, I am back to my Lion. The new log in window is very different from the previous one, and I like its simple interface. One thing I realize is that the resume seems working when I log in: all the previously opened windows are resumed. Another thing I noticed that re-log in after sleep or lock is much faster than before. It takes less than a second to bring me back. I remember that Snow Leopard takes several seconds to resume network connection, specially when Safari is opened. Now everything is back instantly.

Mac Lion Update

I am in the process of updating my Mac OS to Lion. Since I got one new MacBookPro 15 this month. I am entitled to get free update. Here are some notes about the update.

First, I need to get redeem code from Apple. There is Apple web page for Canadian Mac users to get free Lion redeem code. This site is for Canada. I was trying to get it from US Apple site, and I could not pass through. It was hard to find it out from Apple web site. I found it from from MacRumors forum.

At the end of the process, I saved the result as PDF(or print it as PDF). It is critical to remember the redeem code. Then it is very straightforward to get it is from Apple Store. Now it is in downloading process. I started at about 9:00am.



I also found this CNET News article about to burn DVD for Lion Installation. I am going to follow the instruction to give it a try.

At: 10:02, the download is done.



I have installed Lion on my 3 Mac computers. One more to go, but I have to wait to make sure my daughter's Adobe's apps are OK with Lion.

After the installation, there is one new update: iTunes 10.4.1 with support of full screen.



Here is the space difference between installations of Lion and iTunes update:

Command: df -lak	Used(Kilobytes in 1024-blocks)
Before	..,13,796,024
After Lion	...8,780,612
After Update	...9,450,752
Difference (A Lion-B)	-5,015,412
Difference (AU-AL)	669,960

From the appearance, at first glance, it looks like the same as before. However, after playing for a while, I noticed some big differences. For example, srcollbars are different. The default scroll behavior does get awkward, but it is very easy to get used to it.

The biggest issue I have right now is the Preview's SaveAs is gone. I could not use previous Cmd+Shift+s to get difference format for pictures. I have to use Export or Duplicate and Save. The Save dialog does not display file size information. This is a problem for me. I would like the different format to compare the picture size difference so that I'll make decision to save it or not.

Another big change is that Java is not installed by default. I tried to test Adobe PS and it prompt to install Java.

Today I got 5 items of updates: Mac Migration Assistant, iWork, iTunes, RemoteDeskTop, and Safari. Not sure if they are related to the preparation of the new Mac Lion or not. My Macs have not updated yet. I may get updates when my daughter is back tonight, because she has a new MacBookPro purchased last week. She is entitled to get the new update of OS Lion.

iWeb and iDVD Updates

It is close to Lions release. I got the following updates which do not seem related to Lions. I'll not rush to Lions update when it is out because my daughter just purchased MacBookPro 15 about one week ago. She is legible to get free Lions update from App Store. I am not sure if I can use the same one for my other computers or not.
