My xcode download keeps failing due to network error - xcode

My xcode download keeps failing. It gets downloaded completely, but then says 'Failed - Network error'.
I have tried to download twice, switched off and on my mac.
My internet connection is fine.
I am downloading from developer.apple.com
Please suggest how to download Xcode. Mine is an older version of mac - version 10.10.5
so I am trying to download xcode_7.2.1

Apple seems to be having a network issue.
In this answer, they show you how to download the file using curl, and how to resume an ongoing download using -L -C -: https://apple.stackexchange.com/a/253269
Since it's "just" a network issue, you can simply retry until you have the full file. Or you can write a script:
until <curl command copied from chrome> -L -C -
do
echo retrying
done
Hope it helps!

Launching Starlink GAIA on Mac OS: "developer cannot be verified" error

I'm trying to set up Starlink v2018A on Mac OS Monterey. I followed the install instructions on the Starlink website and so the installation seemed to go smoothly. However, now that Starlink is installed, whenever I try to launch gaia I get " "<file_name>" cannot be opened because the developer cannot be verified. ".
I know how to manually work around this for individual files, but when I fix it for one file, the error simply re-occurs for another file.
Has anyone else had this issue and know a quick fix? Or will I just have to manually approve each file?
Thanks!

cygwin install hangs on /etc/postinstall/0p_update-info-dir.dash

I just downloaded https://www.cygwin.com/setup-x86_64.exe
and used a few mirrors like cygwin.mirror.constant.com
w/o success
I read that file /etc/postinstall/0p_update-info-dir.dash
it hangs when running md5sum: ls -n /usr/share/info/*info* | md5sum >/usr/share/info/.stamp.tmp
because neither the file .stamp.tmp nor .stamp.tmp are being created
at the log here there is this:
Cygwin WARNING:
Couldn't compute FAST_CWD pointer. This typically occurs if you're using
an older Cygwin version on a newer Windows. Please update to the latest
available Cygwin version from https://cygwin.com/. If the problem persists,
please see https://cygwin.com/problems.html
but if I try to run md5sum directly it shows the same above warning.
it happens on windowsxp and windows 7
I tried a huge lot of tips and tricks from removing log files to deleting the whole install path to start again but it did not help
If you are being able to install cygwin on 2022, tell me how you did it?
PS.: that warning comes from bin/cygwin1.dll

Unable to open LiClipse 6.1.0 on MacOS/Catalina (10.15.3)

I have downloaded LiClipse 6.1.0 from http://www.liclipse.com/download.html three times (to ensure that I don't have a corrupt/damaged file) and installed it on a MacPro Notebook with MacOS Catalina (10.15.3). I have followed the installation instructions at http://www.liclipse.com/download.html for Native Mac OS Install, but every time I get "“LiClipse.app” is damaged and can’t be opened. You should move it to the Trash."
Since it gets installed without any problem, I think that downloaded file is not corrupted/damaged, but when opening it I always get the warning about its being damaged even when I have run sudo spctl --master-disable to enable apps from "Anywhere" to run.
I would appreciate if anyone who had succeeded in opening it on a MacPro/Catalina would share his/her steps. Thanks.
You can try removing the quarantine flag (when Mac downloads a file it marks it as quarantined and it won't run unless it has an Apple signature -- which LiClipse doesn't have, so, Apple is making it always a bit harder to run files you download).
To remove the quarantine flag, run:
xattr -d com.apple.quarantine <FILE>
(<FILE> being /Applications/LiClipse.app and maybe /Applications/LiClipse.app/MacOS/LiClipse too -- I don't really have Catalina to check).

AUv3 extension is not registered in MacOS

I am trying to write a small MacOS app with AUV3 extension.
I followed all the instructions, however, the extension is not registered in the system. I suppose to see it in the list when I execute:
pluginkit -mv | grep [MY_EXTENSION_NAME]
command, but I see nothing.
Trying to execute command:
pluginkit -a [MY_EXTENSION_PATH]
does not give any error or any other output at all.
syslog - w
also does not shows any error.
There are no compilation errors or even compilation warnings of any kind.
Maybe someone can direct me to some other error log or some tool or verification that can help me. Is there a place where I can read about the registration process and what can go wrong?
I tried:
Xcode 8.2 on El-Capitan
Xcode 9 Beta on High Sierra Beta

XCode 4.3 Command Line Tools Package with Invalid Checksum

The package Apple provides to install the command line tools with Xcode 4.3 is corrupted, and I seem to need it because I'm developing some command line tools.
Has anybody found an alternative Command Line package for Xcode 4.3 from Apple that works or an workaround for the subject?
Xcode includes a new "Downloads" preference pane to install optional components such as command line tools, and previous iOS Simulators.
So, I found a way to do this correctly.
The problem is really in one of the European mirrors from Apple.
The workaround is to:
- Install Tor: https://www.torproject.org/
- Choose a Tor node in the USA
- Logging into your Apple Developer account and download the package
It now opens correctly without any checksum warning.
I solved my own problem of downloading/installing Xcode 4.3.1 "Command Line Tools" by getting them directly from the developer's webpage. The March version yielded a checksum error just like
the download from within Xcode 4.3.1, i.e. Xcode/Preferences/Downloads . But I did have success with the February version of CLT. I don't know why things were out-of-sync.
I had the same problem when trying to install the Command Line Tools from the Downloads tab in the XCode preferences (also downloading from Europe). I fixed it by clearing the dns cache on my system.
This is the Terminal command to clear the dns cache (OSX Lion):
dscacheutil -flushcache
Restart XCode after running this command, it may not fix the problem with the checksum until you do.
try:
defaults write com.apple.frameworks.diskimages skip-verify -bool true
Just add another mirror for the download site:
Use the following to determine a valid ip:
http://www.webmaster-toolkit.com/dns-query.shtml?address=adcdownload.apple.com
and add this to /etc/hosts:
adcdownload.apple.com
Example (ip might already have changed)
64.211.144.168 adcdownload.apple.com.
You can simply click skip while the disk image is verifying. I have installed from a dmg of CLT-4.3 with this problem and built an extensive amount of software with if successfully on my te
