Safer Internet: Offline: Software Updates

Quotes

Definition. software upgrade:...
A client calls to hotline of internet service provider.
Client: "I have a problem, internet stopped working two days ago, neither I nor my son nor anyone else can access it now."

Hotline: "I see. Do you know what's the operating system on your PC?"
Client: "Of course I do,... it's Facebook"
"Chaos reigns within.
Reflect, repent, and reboot.
Order shall return.

Program aborting:
Close all that you have worked on.
You ask far too much.

Windows NT crashed.
I am the Blue Screen of Death.
No one hears your screams.

Yesterday it worked.
Today it is not working.
Windows is like that.

First snow, then silence.
This thousand-dollar screen dies
So beautifully.

A crash reduces
Your expensive computer
To a simple stone.

Serious error.
All shortcuts have disappeared.
Screen. Mind. Both are blank.

There is a chasm
of carbon and silicon
the software can’t bridge.

To have no errors
Would be life without meaning
No struggle, no joy.

Seeing my great fault
Through darkening blue windows
I begin again.

The code was willing,
It considered your request,
But the chips were weak.

Errors have occurred.
We won’t tell you where or why.
Lazy programmers.There is a chasm

Dear Tech Support,
Last year I upgraded from Boyfriend 5.0 to Husband 1.0 and noticed a slowdown in the overall performance, particularly in the flower and jewelry applications that had operated flawlessly under Boyfriend 5.0.

In addition, Husband 1.0 uninstalled many other valuable programs, such as Romance 9.5 and Personal Attention 6.5, but installed undesirable programs such as NFL 5.0 and NBA 3.0. And now...

Summary

"If it ain't broke, don't fix it"?
Even if you don't care about bug fixes or new features, privacy & security updates are very important.
It's a myth (procrastination excuse?) that newer versions are always larger, slower, buggier.
Take note of software upgrade/update notifications, e.g., popups, emails -- -- but don't interact directly with them.
It's better not to click on links/buttons in unexpected notifications, even if they seem from legitimate sources;
browser popups about Flash are a notorious avenue for malware
Instead, check/update officially via app store, vendor, OS/app or settings.
Although most updates are generally reliable, it's a good idea to backup first anyway.
[1] Install Minor/Incremental Updates: System, Apps, Add-ons/Extensions -- within a few days
[2] Install Major Upgrades -- within a few weeks
[2] Consider replacing your device or browser -- if security updates are no longer offered; in the meanwhile, exercise extra caution when online; or run selected apps on a different more secure device.
[2] Don't forget other network(ed) devices, e.g., router, smart TV, IoT
[3] Run software and hardware diagnostics/repair utilities

When, What to Update: System, Apps, Add-ons

Backup!
If you minimize number of applications and add-ons, esp. if infrequently or not used (see Erasing section), there will be fewer items to update.
Each user will have different risk vs. benefit tradeoffs for what & when to update
Most tech-savvy user in family might do updates for everyone (whose accounts lack admin privileges)
Update sooner if the system or app security fixes are critical, i.e., browser, email, network, cloud
It's usually ok to wait a few days -- for a few weeks for major versions -- if you're travelling or extra busy, or to research incompatibilities.
Many bugs have already been detected and fixed during wider beta testing by developers (and daring users)
Any problem with a software update itself is usually remedied in a day or two -- plus, upgrade servers will be more responsive
Current/recent OS versions:
Usually, the latest version numbers/dates will be listed below -- and on Course Updates page:
The labels and color-coding suggest status/urgency for upgrading:
green: up to date
lighter green: Recent; incremental; upgrade soon
orange: Old; major; upgrade when convenient
red: Obsolete; upgrade asap, or replace -- if internet is used and security upgrades no longer avail

Operating System

system: e.g., Android, iOS, macOS (formerly "OS X"), Windows
for checking version / installing system update:
iOS: Settings > General > About : Version
iOS: Settings > General > Software Update
macOS: [apple] > About
macOS: System Preferences > Software Update
Win: Settings > System > About
Win: Settings > Update & Security > Windows Update
[2] Update software/firmware on other connected devices, e.g., router, smart TV
[3] Test/beta official OS versions -- only if you are a developer, bugged by a bug, can't live without a new shiny feature, or crave living on the 'bleeding edge'.

Apps

Individual apps: check for updates via app store, upon startup (app preference), or manually (via menu)
Ok to ignore updates for apps that you never use, e.g., built-in apps like GarageBand -- but why not remove if unneeded, or offload if easily re-downloaded?
Install system & application updates only from official store, from within apps, or reputable developers
Some apps offer option of automatically downloading and installing updates; it's up to you; I prefer to backup before installing most updates.
[2] Generally, don't download from 3rd party sites, e.g., CNet, Soft32, ZDNET, download.com, etc.
[3] Don't jailbreak your device with an unofficial OS, so that you can install nifty but questionable apps.

iOS: Settings > (your acct) > Family Sharing
macOS: System Preferences > iCloud > Manage Family
[3] macOS: System Preferences > Security & Privacy > 'app was blocked from opening because it is not from an identified developer' > Open Anyway

Add-ons: Plugins, Extensions

add-ons customize/extend an app, esp. a browser
Once installed, most browsers check/update automatically, or via sytstem preference
Do not update browser extensions, e.g., Flash, or apps when prompted via a browser popup -- use app store, or app or extension's own 'Check for Updates' command
Look for install options -- often checked by default -- that might install unwanted extensions or adware, or change settings (home page, search engine); e.g., Oracle's Java installer
plugins: e.g., Adobe Flash; Oracle Java -- or consider uninstalling altogether
extensions: e.g., Adblock Plus, HTTPS Everywhere
macOS: Safari > Preferences > Extensions > Updates : Install Updates Automatically
macOS: System Preferences > Flash Player > Advanced > Updates

[1] Install Minor/Incremental Updates, e.g., #.1

Backup -- both incremental and clone -- before cleanup; again before actual installation;
see When, What to Upgrade; Backup section
If you always keep your device up-to-date, it should be easier to migrate to future system & app releases
You can usually wait a day or two -- or even longer if there are no security fixes for your particular device
Update may contain bug fixes, and minimal new features
Allow enough time for backup, download and install -- probably not before a trip or big presentation; updates usually go smoothly, but allow a little more time in case you need to troubleshoot or restore a previous system version.

Android

[Refs:Android]

iOS

[Refs:iOS]
iOS: Settings > General > Software Update
iOS: App Store > Updates
iOS users may want to use iTunes to update iOS: easy to backup first
for OTA (over the air) updates via WiFi or cellular
< iOS9: update can fail due to low device memory
≥ iOS9: update can be slower; apps are removed/reinstalled if needed to create temporary space

macOS

[Refs:macOS]
Out-of-cycle Security or Supplemental Updates may also be available, with no change to system version #
macOS: [apple] > About > Software Update
macOS: App Store > Updates -- macOS and selected apps
macOS (10.14): System Preferences > Software Update
macOS: System Preferences > App Store: download/install, password

Windows

[Refs:Windows]
Win: Settings > Update & Security > Windows Update

[2] Install Major OS Updates, e.g., #.0

Backup -- both incremental and clone -- before cleanup or running diagnostics;
again before actual installation; see When, What to Upgrade; Backup section
Install incremental or other updates to current OS and apps -- including Safari, iTunes for macOS -- before installing major updates
Allow even more time for backup, download and install -- to anticipate and remedy incompatibilities -- and if things don't go smoothly, for troubleshooting or restoring previous system version
Usually released about once/year: more major fixes, new features and possible incompatibilities
iOS: you should upgrade 'as soon as possible'; usually less complex than desktop upgrades; security fixes sometimes available for previous iOS version
macOS: incremental security fixes are still provided for previous system and browser for 1-2 years, so if there are really major changes, e.g., app incompatibility, user interface makeovers, missing features, performance issues, you could delay your upgrade -- though not indefinitely
Generally, you could wait a week or two for ".1" version to be released to avoid major bugs, especially if there are no critical security fixes and there are significant changes, e.g., file system
If there are multiple devices in a family, upgrade one first to test the process & outcome before upgrading others.
When you are ready to upgrade:
Read articles here about latest version, e.g., Android, iOS, macOS, Windows, or buy Take Control e-books to find out more about what's changed, compatibility/adequacy of your hardware (to run new os) and of apps (with new os), cleanup & backup steps, new features that you might actually like to have (or old features that might be removed that you can’t live without), installation advice
Remove unused applications and browser add-ons -- see Erasing section
Check if new OS version is incompatible with any important applications you have, e.g., upgrade info, release notes, vendor sites
Apple: macOS versions, compatibility; iOS, iPadOS updates
macOS: (apple) > About This Mac > System Report > Software > Applications: 64-bit(Intel) -- some 32-bit apps may still continue to work under High Sierra.
iOS10: Settings > About > Applications: 'these apps may slow down your iPad and will not work with iOS 11 if they are not updated'
For incompatible apps, consider upgrading version or finding a (free) alternative.
For example, instead of Microsoft Office 2011, which may not work with macOS 10.13 (High Sierra): HS 32-bit app incompatibility; plus, Microsoft has stopped providing support and security patches
offline apps: Microsoft Office 2016 -- $$; Steve's spouse upgraded to this
macOS/iOS iWork suite: Pages, Numbers, Keynote -- free; Steve switched to these
Open Office, LibreOffice, NeoOffice -- free
SoftMaker: Free Office (free); Softmaker Office: Std ($20+) / Pro; comparison
cloud-based storage & office suite (via browser): Microsoft: OneDrive: Word, Excel, PowerPoint Online -- free;
Microsoft 365 -- subscription; includes apps (And,iOS,Mac,Win), 1Tb OneDrive cloud storage, 60 Skype minutes/mo.
Google Drive: Docs, Sheets, Slides -- free
Apple's iCloud: iWork (Pages, Numbers, Keynote) -- free
[2] Check disk permissions, repair (less necessary recently)
macOS (< 10.10): Disk Utility > Repair Permissions -- or run Maintenance (or Onyx) utility
[3] Restart from Recovery partition; check main disk; repair (if necessary)
macOS: restart w/ cmd-R > OS X Utilities > Disk Utility > Repair Disk
[3] Check hardware, e.g., memory
macOS: restart w/ D key; diagnostic runs automatically

[2] Replace Device?

Strongly consider replacing your device if security/privacy problems are no longer patched in your OS version -- and you can't upgrade, e.g.,
if your computer OS is more than 1-2 major versions behind -- see macOS, Win
usually if your tablet/phone OS is 1 or more major versions behind -- see Android, iOS
Your device doesn't support a newer OS -- or needs extra memory that you cannot (or do not want to) add
Apps you rely on are no longer provided/supported on your old OS (e.g., 32-bit when 64-bit will be required) -- and no updates are available
In the meanwhile, use an actively maintained browser, e.g., Firefox, Chrome -- rather than built-in browser, i.e., macOS Safari, Windows IE; and consider using the device only for casual (non-encrypted) browsing
Do you need just browsing, email, basic document creation/editing, and simple photo manipulation? If so, you might consider a tablet (iPad) or Chromebook -- less expensive, and much simpler to maintain/update than a full-blown desktop or laptop computer with macOS, Windows or Linux.
When purchasing a new device, especially a subsidized or less expensive one, request that vendor remove pre-installed bloatware, crapware, adware
If you're switching between different OS (versions or vendors), check if migration tools are available for contacts, bookmarks, settings, photos, accounts, etc.
When donating / discarding old device -- see Erasing section
