Can I copy installESD.dmg to DVD or Flash and install on a different Mac?

I have downloaded Lion to my Macbook Pro. We live in a rural area and are on a "low speed" high speed internet connection, so it took me ~24 hours to download. I have not yet begun the installation process, and have copied the installesd.dmg from the install folder to my desktop. We have 3 macs in our house, and I don't want to have to try to download again, as the process is so slow. Can I just copy the installesd.dmg to a DVD or flash drive to install it on the other 2 macs?
If this is possible, do I have to do anything special? Can I install from the flash or DVD or do I need to copy onto the target mac first? Although both other macs are backed up using time machine, I'm a little nervous about just launching an installation without really knowing what I'm doing.

No, you can't just copy the InstallESD.dmg file to a DVD or USB thumb drive IF you want to boot from those media and install Lion. You can follow the instructions here to burn a bootable DVD or restore a bootable USB thumb drive. You have already completed some of the steps. Just follow the steps to create a bootable DVD or USB thumb drive. The bootable media allows you to use Disk Utilities or the other Mac OS X Utilities if you need to prepare the volume you're installing on.

You can do it. This article from Macworld will be helpful to you:

I recommend the "brute-force" method.
Just make sure you have your data backed up properly!

Lion InstallESD.dmg not found after download and install on my macbook pro; I need it for built a install-dvd

I want to built a install-DVD from Lion. The finder doesn't find the *.dmg-file from Lion on my MacBook Pro. Who knows a solution? How can I download the Install-Image again wthout to update my Notebook with Lion again. In the appstore my purchase is marked with "installiert". If I click with the right button to get another option for a download - no command.

I've tried your suggestion to sporty54 but, when I Option click the purchases icon in the App Store, it only shows my other installed items as here:-
I don't know what 'MAS' refers to. Is this another place on my iMac where I should look and, if so, where is it?

How can I copy an audio effect from a clip and paste it to another clip in the same timiline...With FCPro 7 it was all so fast........

The advantage goes to FCP7 if you allow that it can copy and paste filters, audio and video, transformations, and other attributes separately.
You can do that in FCPX too, as all the things you cited are listed separately in the inspector.
Here's a little gotcha. Let's say you've color corrected a few clips and you've applied an effect to one and want to paste it the other clips. You switch off color correction and copy the clip. You select the other clips and paste effects. What do you think happens? The effect is applied, but the color correction is applied as well, only it's switched off as it was in the first clip, so all the color correction on the other clips is lost. Fun, eh?
I'll try to replicate your gotcha - but no, that doesn't sound like fun at all!

I can't copy my old iPhoto library from a external HD to my new mac?

Hi. I just bought a new mac and want to have all my old iphoto pictures from my old mac into my new iPhoto library. I've tried to copy the old iPhoto library into a external HD(works fine), but the problem is that I can't copy it out from the external HD an in to my new mac again. It just say that it doesn't work because it doesnt have enough storage.
I don't get why it would say that, because the old iPhoto library is 89.55 GB and I haven't used any memory at all on my new macbook pro, and my old macbook pro has memory enough to have the iPhoto library on it (the mac is 5 years old and has almost a full memory), so why can't my new macs memory manage the iPhoto library when my old mac can? It doesn't make sense at all.
I've googled it, and it says everywhere that it should work by simply copy to external HD and move over the library from there and into the pictures folder, but this definitely doesn't work for me.
I hope that some please can help me with this, I don't know what do to.

How can I with my iCloud back from my iPhone and iPad to a new Mac?

How can I swith the iCloud back up from my iPad and Iphone to a different Mac?

Your Apple service centre is very good.. they mostly refuse to help in any way.
You need a USB to sata converter cable and power supply or a USB disk holder.. SATA type.. although that is pretty universal now.. they are only a few dollars from most large computer stores or ebay. Plug the usb drive into the computer and copy the contents over to the TC. using ethernet will help btw.. if you only have the air buy a USB to ethernet or Thunderbolt to ethernet (if you have the latest one).. they are available from apple at reasonable prices.
Then you can copy the sparsebundle across..

BUT I have to say I don't recommend it.. I think you are better starting with a new backup and keep the old disk as an archive..

I have a late 2012 iMac and a late 2009 mac mini. I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.

I have a late 2012 iMac and a late 2009 mac mini. I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.
According to Cruicial my mac mini could use:
Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-8500
Specs: DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.35V • 512Meg x 64
Also According to Cruical my iMac uses:
Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-12800
Specs: DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V
I want to increase the ram in both computers.
So, can I put the iMac ram in my mac mini and then I'd only have to buy ram for my iMac? Naturally the ulitmate test will be when I actually install it, but having an expectation of success or failure will allow me to plan on what to spend money on.
Thanks,
Bear

Thanks for the responses. I probably wont even try as my priority is Ram for the mac mini. 2 is not enough. 8 for my imac is okay for now.
Somewhere I thought I'd heard that faster Ram would simply clock at the lower speed. It seems that I am incorrect.
Thanks,
Bear

How can I format an HD with System 10.4 and install Leopard Snow?

How can I format an HD with System 10.4 and install Leopard Snow?

You need to partion the hard drive using Disk Utility. On one partition install 10.4. On the other 10.6. As a note I trust you are doing this on a MBP and not a PPC Mac because 10.6 won't install.

Hello, I purchased Adobe as a download a few years ago and installed in on a Mac Pro. I would like to uninstall it on that mac and install it on a new Mac Pro. Any idea how I can do that?

Just download, install, and activate using your serial number. You are allowed to have the software installed and activated on two machines. If you do not wish to retain the original installation as a backup you can deactivate it by opening one of the programs and choosing Help -> Deactivate.
Here is a general link for where you can find download links...
Download and Installation Help -
https://helpx.adobe.com/download-install.html
If you would like a more direct link you will need to name the software and the version.
If you need your serial number you should be able to find it in your Adobe account online if you registered the software when you first installed it.

Can I import an MP4 or FLV to Flash and make it an editable .fla file?

Can I import an MP4 or FLV to Flash and make it an editable .fla file?

Thanks for helping me.
It's a vector animation that was made in flash and exported into a swf I believe and then posted on a website and on youtube. I have the mp4 ad the flv that I have converted from the online file using an online tool. I would like to use it as a base for my own video and just switch out some of the frames and characters/backgrounds - is that possible in Premier?

Does MacOS recognize Windows directory structure? Can I move an entire folder (consisting of subfolders and files) from Windows to Mac?

Can I move an entire folder (consisting of subfolders and files) from Windows to Mac?

Mustafafromnc,
if you’re talking about a USB drive, then it will probably have an exFAT filesystem. Modern versions of OS X can read from and write to exFAT filesystems without problems, so you would be able to move Windows folders, subfolders, and files from an exFAT filesystem to an OS X filesystem.
