OT-05 · Legacy & utilities Free · open source

The outer belt.

Two free, open-source tools for the machines the paid apps don't cover: Intel Macs and iOS. No licence keys, no accounts. Just the repos.

01 / OptiMac for Intel Macs

Old silicon,
not retired.

A command-line optimiser for Intel Macs. The same deep clean and maintenance, with no interface to draw.

zsh · optimac-intel

Built for Intel

The same clean and maintenance, on the hardware OptiMac won't run on.

Two commands

One reports what it can reclaim. The other runs the periodic scripts.

Nothing left running

No menu bar icon, no helper, no window. It does the job and hands the prompt back.

02 / OptiTranslate for iOS

Any page,
translated.

A Safari userscript for iPhone and iPad. It detects foreign-language pages and translates them on the spot, with your choice of engine.

Translated in place

The page stays where it is. The text just changes language.

Three engines

Google, Yandex or Bing. They disagree often enough that having the choice matters.

It notices first

Open a page in another language and it offers before you go looking.

04 / Alternatives

Looking for an alternative?

Free and open source, for the machines the paid apps do not cover.

Free CleanMyMac alternative for Intel Macs

The deep clean and the maintenance run from the command line, so an aging Intel Mac spends nothing on drawing an interface. No licence key, no account, no cost.

OnyX alternative from the terminal

The macOS periodic scripts, the dyld cache and the Spotlight index, refreshed with one command rather than through a settings pane.

Alternative to paid cleanup subscriptions

GPL-3.0, source in the open, nothing collected and nothing sent anywhere. Read it, fork it, audit it.

Manual terminal maintenance alternative

The commands most people copy from forum posts, collected into two flags that report what is reclaimable before anything is removed.

Safari translation extension alternative for iPhone

OptiTranslate is a userscript rather than an App Store extension: it detects a foreign-language page and offers to translate it in place, on iPhone and iPad.

Google Translate alternative on iOS

Three engines to choose between, Google, Yandex and Bing, so you can pick whichever reads better for the language in front of you.

05 / Questions

Straight answers.

What is in OptiExtras?

Two free, open-source tools: OptiMac for Intel, a command-line optimiser for Intel Macs, and OptiTranslate, a Safari userscript for iPhone and iPad.

Is it really free?

Free and open source under GPL-3.0. No licence keys, no accounts, no catches, just the repos.

Does OptiMac (the paid app) run on Intel Macs?

No. The paid OptiMac is written for Apple Silicon only. Intel Macs are served by the free OptiMac Intel CLI here, which gives aging hardware the same level of optimisation.

What does the deep clean do?

optimac --deep-clean scans caches, logs and leftovers and reports what is reclaimable, 4.2 GB across 1,318 files in the example run, before removing anything.

What does maintenance do?

optimac --maintenance runs the macOS periodic scripts and refreshes the dyld cache and Spotlight index, restoring factory-fresh behaviour on an aging machine in well under a minute.

Why a command-line tool rather than an app?

Zero GUI overhead. On an aging Intel Mac, a heavyweight Electron cleaner consumes RAM simply to draw its own interface and makes the machine slower still. A CLI does not.

What is OptiTranslate for iOS?

A Safari userscript for iPhone and iPad. It detects foreign-language pages and offers to translate them on the spot.

Which translation engines can it use?

Google, Yandex or Bing, your choice, so you can pick whichever gives the better result for a given language.

Does any of this track me?

No tracking and no telemetry in either tool. That is a large part of why they exist.

Where do I get the source?

Both tools live in the OptiTools repositories, linked from the buttons above, and are licensed under GPL-3.0 so you can read, fork and audit them.
